• [Right Triangle Only] Pythagorean Theorem: a² + b² = c²

Explanation:

Step 1: Define

We are given a right triangle. We can use PT to solve for the missing length.

Step 2: Identify Variables

Leg a = 12

Leg b = x

Hypotenuse c = 20

Step 3: Solve for x

1. Substitute: 12² + x² = 20²
2. Isolate x term: x² = 20² - 12²
3. Exponents: x² = 400 - 144
4. Subtract: x² = 256
5. Isolate x: x = 16
