I can apply the Pythagorean Theorem to find the missing side length of a right triangle.
- 1
The Pythagorean Theorem can only be used to find the missing side length of right triangles.
- 2
The formula for the Pythagorean Theorem is a² + b² = c², where 'c' always represents the hypotenuse, which is the side opposite the right angle.
- 3
When finding a missing leg, you'll need to subtract the known leg squared from the hypotenuse squared before taking the square root to find the missing side length.
