Help! My sister needs help, I don't know how to explain this to her, can anyone please explain how??
Directions: Determine whether each triangle with the given side lengths is a right triangle. Write yes or no.

EX: 10 ft, 24 ft, 25 ft

Thanks!

Does $10^2 + 24^2 = 25^2$?

Note: The hypotenuse is the longest side of a right triangle.

3. ## triangle

so, we can see it is not a right triangle, because if it were, the Pythagorean theorem would work, but it does not, so it is not a right triangle. it would be if the side were 10, 24 and 26.
