The three squares below join together to form a right triangle. The area and the perimeter for two of the squares is shown. Find the side length of the largest square.

answer: add the !

step-by-step explanation: then we will answer

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
