Question

The side lengths of a triangle are 9, 12, and 15. Is this a right triangle?​

Answer 1

Yes, it is a right triangle.

Explanation:

To check if the sides are a right triangle, check if the sum of the squares of the two smaller sides equals the length of the square of the longest side. In this case:

9^2 + 12^2 = 225

15^2 = 225

225 = 225

So, these side lengths do form a right triangle.

Answer 2

Yes, this is a right triangle.
