Question

Do these side lengths make a right triangle? 3, 4, 5 *

Answer 1

This is a right triangle

Explanation:

We can check if this is a right triangle by using the Pythagorean theorem

a^2 +b^2 = c^2 where a and b are the legs and c is the hypotenuse

3^2+4^2 = 5^2

9+16 = 25

25=25

This is true so it is a right triangle
