Question

True Or False: A triangle with the side lengths of 9, 12, 17 is a right triangle

Answer 1

not a right triangle

Explanation:

We can use the Pythagorean theorem to see if it is a right triangle

a^2+b^2 = c^2

9^2+12^2 = 17^2

81+144 =289

225 = 289

This is not true so it is not a right triangle
