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

Step-by-step 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
