Which side lengths form a right triangle?

A.)5,6,7
B.)6,8,10
C.)9,9,18

The answer to your question is the letter B

Step-by-step explanation:

Process

To prove if three lengths form a right triangle they must agree with the Pythagorean theorem.

                      c² = a² + b²

c must be the longest side.

a)  

                      7² = 5² + 6²

                      49 = 25 + 36

                      49 ≠ 61                   These sides do not form a right triangle

b)                   10² = 8² + 6²

                     100 = 64 + 36

                     100 = 100              These sides form a right triangle

c)                 18² = 9² + 9²

                   324 = 81 + 81

                   324 ≠ 162                These sides do not form a right triangle
