How do you find the hypotenuse of a triangle?

By the formula (hypo) square = (side1square) + (side2square)

Identify the legs and the hypotenuse of the triangle. You know that the triangle is a right triangle since the ground and the raised portion of the porch are perpendicular-this means you can use the Pythagorean Theorem to solve this problem. Identify a, b, and c. Use the Pythagorean Theorem to find the length of c.
