THERE ARE TWO special triangles in trigonometry. One is the 30°-60°-90° triangle. The other is the isosceles right triangle. They are special because with simple geometry we can know the ratios of their sides, and therefore solve any such triangle.

Note that the smallest side, 1, is opposite the smallest angle, 30°; while the largest side, 2, is opposite the largest angle, 90°. (Theorem 6). (For, 2 is larger than

. Also, while 1 :

: 2 correctly corresponds to the sides opposite 30°-60°-90°, many find the sequence 1 : 2 :

easier to remember.)

Here are examples of how we take advantage of knowing those ratios. First, we can evaluate the functions of 60° and 30°.

Answer. For any problem involving a 30°-60°-90° triangle, the student should not use a table. The student should sketch the triangle and place the ratio numbers.

Answer. According to the property of cofunctions, sin 30° is equal to cos 60°. sin 30° = ½.

1 : 2: SqRt 3

The cotangent is the ratio of the adjacent side to the opposite.

Therefore, on inspecting the figure above, cot 30° =

= .

Or, more simply, cot 30° = tan 60°.

As for the cosine, it is the ratio of the adjacent side to the hypotenuse. Therefore,

cos 30° =

= ½

Before we come to the next Example, here is how we relate the sides and angles of a triangle:

If an angle is labeled capital A, then the side opposite will be labeled small a. Similarly for angle B and side b, angle C and side c.

Example 3. Solve the right triangle ABC if angle A is 60°, and side AB is 10 cm.

Solution. To solve a triangle means to know all three sides and all three angles. Since this is a right triangle and angle A is 60°, then the remaining angle B is its complement, 30°.

Again, in every 30°-60°-90° triangle, the sides are in the ratio 1 : 2 :

, as shown on the left.

When we know the ratios of the sides, then to solve a triangle we do not require the trigonometric functions or the Pythagorean theorem. We can solve it by the method of similar figures.

Now, the sides that make the equal angles are in the same ratio. Proportionally,

To produce 10, 2 has been multiplied by 5. Therefore,

will also be multiplied by 5. BC is 5

cm.

In other words, since one side of the standard triangle has been multiplied by 5, then every side will be multiplied by 5.

Again: When we know the ratio numbers, then to solve the triangle the student should use this method of similar figures, not the trigonometric functions.

(In Topic 10, we will solve right triangles whose ratios of sides we do not know.)

Problem 3. In the right triangle DFE, angle D is 30° and side DF is 3 inches. How long are sides d and f ?

1 : 2: SqRt 3

The student should draw a similar triangle in the same orientation. Then see that the side corresponding to was multiplied by .

Therefore, each side will be multiplied by . Side d will be
1 = . Side f will be 2.

Problem 4. In the right triangle PQR, angle P is 30°, and side r is 1 cm. How long are sides p and q ?

Problem 5. Solve the right triangle ABC if angle A is 60°, and the hypotenuse is 18.6 cm.

The area A of any triangle is equal to one-half the sine of any angle times the product of the two sides that make the angle. (Topic 2, Problem 6.)

In an equilateral triangle each side is s , and each angle is 60°. Therefore,

A = ½ sin 60°s².

Since sin 60° = ½,

A = ½· ½ s² = ¼s².

Problem 7. Prove: The area A of an equilateral triangle inscribed in a circle of radius r, is

"Hero, don't just focus on clearing the tower."

This kind of advice is typically given to players to encourage a more strategic approach to the game rather than focusing solely on immediate objectives like destroying enemy towers. Here are a few reasons why this advice is valuable:

Map Control: Focusing solely on towers can lead to neglecting other parts of the map. Enemies might be taking objectives elsewhere, like killing creeps in other lanes, taking out enemy heroes, or even pushing towers in other lanes. A well-rounded strategy considers the entire map.
Team Fights: Heroes often have abilities and roles that are crucial in team fights. Focusing too much on lanes and towers can mean missing opportunities to team up with your team to take out enemy heroes, which can significantly turn the tide of the game.
Farm and Gold: While lanes are a source of gold and experience, heroes can also gain gold and experience from killing enemy heroes and creeps in the jungle or other lanes. A balanced strategy ensures you're not missing out on gold and experience that could make you or your team stronger.
Positioning and Game Knowledge: Sometimes, heroes might need to position themselves for future team fights or objectives. This means not just focusing on the current task (like clearing a tower) but also thinking about positioning for future skirmishes or taking strategic points on the map.
Items and Builds: Depending on the hero and the game's progression, focusing too much on towers might not allow for optimal item building or leveraging abilities at the right time. Strategic play involves considering what items to buy and when, which can significantly affect how you approach lanes, fights, and objectives.

In essence, the advice encourages players to think about the broader strategy of the game, consider their role within their team, and balance their immediate actions with long-term strategic goals.

Common mistakes to avoid

Selling/consuming defensive options too early for marginal offense.
Overstacking a mechanic without base support (e.g., crit builds without crit rate).
Ignoring item descriptions that break synergies (negative side-effects).
Upgrading niche skills before core ones.
Chasing immediate kills at the expense of resource sinks (healing, rerolls).

Hero: Don’t Just Focus on Clearing the Tower – Value Every Step of the Journey

In nearly every role-playing game (RPG) or gacha game, the "Tower" stands as the ultimate proving ground. It looms on the horizon—a spire of challenge, reward, and prestige. Players spend weeks optimizing teams, farming artifacts, and studying enemy patterns, all with one obsessive mantra: Clear the Tower.

But fixating solely on the summit is a trap.

The most seasoned players—the true heroes—know a secret that leaderboards often obscure: The journey through the Tower is more valuable than the act of clearing it. Hero- don-t just focus on clearing the tower -v...

4. Remember the Story

Many Towers hide narrative fragments—letters, flashbacks, environmental details. Rushing skips them. The hero who reads every stone on the path understands why they fight. Purpose fuels persistence longer than any reward screen.

Example micro-build plans

Defensive-scaling: Prioritize max HP, regen/shield, AoE clear. Upgrade defensive passives then your main clear ability.
Burst-finisher: Build crit or multiplier synergy but secure at least one control and a heal; time big upgrades when you have reliable uptime on the multiplier.
Control/utility: Invest early in CC duration and cooldown reduction; later convert utility into damage through item synergies.

The “Tower Blindness” Syndrome

Let’s define the problem. “Tower Blindness” is the player tendency to evaluate every decision based on a single metric: Can this clear the next floor?

This manifests in three toxic behaviors:

The “Fodder Mentality” – You pull a new hero, check their tier list ranking, and if they aren’t S-tier, you immediately label them “food” for ascending your meta heroes. You never read their lore. You never experiment with their unique kit. They are statistics to be consumed.
The Linear Rush – You auto-resolve battles, skip cutscenes, and ignore character quests because “they don’t give tower climb materials.” You reach floor 200 with a team of overpowered, soulless automatons who have zero synergy beyond raw numbers.
The Burnout Cycle – You hit a wall. The tower stops being fun. You blame the game’s difficulty, not your approach. You consider quitting because the “climb” has become a job.

Here’s what the games don’t tell you: the tower is a distraction. A shiny, vertical ladder meant to keep you chasing numbers. The real game—the strategic depth, the hidden bonuses, the unbreakable team synergies—lives in the stories of your heroes.

The Lesson

So, Hero, take a breath. You have your sword, your spell, or your spreadsheet. You are ready to conquer. But as you stand before that final gate, ask yourself:

Am I just trying to escape this tower, or am I mastering it?

Don't just clear the level. Learn the lesson. Because trust me—there is always another tower.

In Hero Wars, the "don’t just focus on clearing the tower" strategy advises against rapidly increasing Team Level, as tower difficulty scales with player level and can lead to a "difficulty trap". To successfully climb, players should focus on maxing a small core team, utilizing manual control for energy management, and using the retreat trick to keep heroes alive for daily rewards.

It looks like you’re trying to share or refine a piece of advice for a game strategy, likely related to a tower-climb or rogue-like genre.

While "Hero—don't just focus on clearing the tower" could also refer to a metaphorical "hero's journey" or a specific anime/manga quote, I'll assume you are looking for a stronger version of this gaming tip.

Here are a few ways to punch up that text depending on the "vibe" you want:

The Strategic Approach: "Hero—don’t just focus on clearing the tower; prioritize resource management and buff synergy to survive the higher floors."

The Dramatic Approach: "Hero, do not mistake reaching the summit for victory. If you ignore the relics along the way, the tower will eventually become your tomb."

The Short & Punchy Version: "Focusing only on the climb is a rookie mistake. A true hero farms the floors before facing the peak."

Was this meant to be a tip for a specific game like AFK Journey or Tower of God, or were you looking for a more thematic/story-driven rewrite?

Example (worked)

Scenario: Repeated bugs after weekly deploys.

Visible problem: Production crashes after each release.
Quick fix: Roll back deploys or add more tests to that module.
Root causes: Rushed releases, poor QA pipeline, unclear ownership, cultural pressure.
Systemic intervention: Implement CI/CD with automated tests + clear release checklist + rotating on-call ownership.
Trade-offs: Slower release cadence initially vs. long-term reliability and developer morale.

Typical decision checklist (each floor/node)

Problem 8. Prove: The angle bisectors of an equilateral triangle meet at a point that is two thirds of the distance from the vertex of the triangle to the base.

Let ABC be an equilateral triangle, let AD, BF, CE be the angle bisectors of angles A, B, C respectively; then those angle bisectors meet at the point P such that AP is two thirds of AD.

For, since the triangle is equilateral and BF, AD are the angle bisectors, then angles PBD, PAE are equal and each 30°;
and the side BD is equal to the side AE, because in an equilateral triangle the angle bisector is the perpendicular bisector of the base.

But AP = BP, because triangles APE, BPD are conguent, and those are the sides opposite the equal angles.
Therefore, AP = 2PD.
Therefore AP is two thirds of the whole AD.
Which is what we wanted to prove.

Here is the proof that in a 30°-60°-90° triangle the sides are in the ratio 1 : 2 :

. It is based on the fact that a 30°-60°-90° triangle is half of an equilateral triangle.

Draw the equilateral triangle ABC. Then each of its equal angles is 60°. (Theorems 3 and 9)

Draw the straight line AD bisecting the angle at A into two 30° angles.
Then AD is the perpendicular bisector of BC (Theorem 2). Triangle ABD therefore is a 30°-60°-90° triangle.

Therefore in a 30°-60°-90° triangle the sides are in the ratio 1 : 2 :

; which is what we set out to prove.

Corollary. The square drawn on the height of an equalateral triangle is three fourths of the square drawn on the side.
