#### Answer:

They DO represent the measures of the sides of a right triangle.

#### Explanation:

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.
