How do you use the Pythagorean Theorem to determine if the following three numbers could represent the measures of the sides of a right triangle: 9 in, 12 in, 15 in?
They DO represent the measures of the sides of a right triangle.
The Pythagorean Theorem states that:
The hypotenuse will always be the longest side of the right triangle, so in this case, 15 is the hypotenuse.
Therefore, 9 in, 12 in, and 15 in are the measure of the sides of a right triangle.
