Al's Supply sold a chain saw to Mark's Lumber. The list price was $1,250. Al's Supply offered a chain discount of 6/3/1. What was the net price of the chain saw?

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.
