State the Pythagorean Theorem and what we use it for

The Pythagorean Theorem is used ONLY in right triangles, to find ONE unknown side as long as we have the other two.

c = hypotenuse (longest side, opposite the right angle)

a, b = the other legs of the triangle

2

Find the hypotenuse:

c2 = a2 + b2

c2 = 52 + 62

c2 = 25 + 36

c2 = 61

take the square root of both sides

c = 7.81
