The side lengths of different triangles are given. Which triangle is a right triangle?

Without having any of the side lengths, we would only be able to identify a right angle if there is a small square in the corner of any of the angles. That would indicate a right angle and there for a right triangle.

With the side lengths, you can go by the pythagorean theorem or if side A and side B equal side C or the hypotenuse (the longest side, which is alway directly across from the right angle.)

A + B = C it would be a right angle.

step-by-step explanation:

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6
