Question

Tell whether the triangle with each set of side lengths is a right triangle.

Answer 1

Explanation:

For a right triangle to exist, the sum of the squares of the lengths of the sides must equal the square of the 3rd side.

Take a look at {10, 24, 26}: 100 + 576 = 676, which is the square of 26. So, YES, these side lengths indicate that we have a right triangle.
