1. Section 11.6 Pythagorean Theorem

2. Pythagorean Theorem: In any right triangle, the square of the length of the hypotenuse equals the sum of the squares of the lengths of the legs.

3. Formula: c is always the hypotenuse

4. Find the missing side length 1.a = 12, b = 16, c = _________

5. 3. a = ______, b = 10, c = 16

6. Converse of Pythagorean Theorem If the sum of the squares of the legs of the triangle is equal to the square of the hypotenuse, then the sides form a right triangle.
