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

The Quest for the APK: A Technical Detective Story

Searching for the Prime APK specifically for 4.4.4 today is a journey into the darker corners of the web. The Google Play Store has long since cut ties with devices running KitKat; the current version of Nova requires much newer Android iterations to function.

The user searching for this is likely holding a piece of history—a Samsung Galaxy S3, an LG G2, or perhaps a Google Nexus 5 that has been pulled from a dusty drawer. The challenge is that software architecture has shifted.

Modern APKs are built for newer Android runtimes (ART) and architecture standards. Attempting to install a modern launcher on a KitKat device usually results in a "Parse Error" or a crash. You need the legacy build. You need the version that still remembers the logic of 2014.

However, this search carries a significant risk. Scouring third-party APK repositories (like the Internet Archive or legacy mirror sites) for a specific version of Nova Prime compatible with 4.4.4 exposes the user to the classic threat model of the Android ecosystem: malware. Old software often contains old vulnerabilities, and repackaged "Prime" APKs are a favorite vector for injecting adware into unsuspecting legacy devices.

The Year Android Grew Up

To understand why someone would want Nova Launcher on Android 4.4.4 (KitKat), you have to remember the state of the world in late 2013. This was the moment Android transitioned from a clunky, geeky experiment into a polished, mature operating system.

Android 4.4.4 was the final, stable iteration of KitKat. It was lean, efficient, and famously capable of running on devices with as little as 512MB of RAM. It was the era of the "Holo" aesthetic—dark grays, neon blue highlights, and a distinctively futuristic, almost cyberpunk user interface.

But for power users, the default interface was never enough. We needed control. We needed Nova Launcher.

Back then, Nova Launcher Prime wasn't just an app; it was a rite of passage. It was the tool that allowed us to break the grid. While stock Android locked you into rigid icon arrangements, Nova introduced the concept of infinite scroll, customizable grid sizes, and the holy grail of customization: gesture controls.

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.
