Section 11.6 Pythagorean Theorem

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.

Formula: c is always the hypotenuse

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

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

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.

9.9, 16, 20

The Distance Formula The distance formula can be used to find the length between any two points on a coordinate plane.

Formula:

Find the distance between any two given points. 1.A(5, 8) and B(-7, 8)

2.K (-4, -5) and H (-4, 6)
