Which of the following measurements could be the side lengths of a right triangle?

A. 55 in, 88 in, 110 in
B. 66 in, 88 in, 132 in
C. 66 in, 88 in, 110 in
D. 66 in, 99 in, 110 in

C. 66 in, 88 in, 110 in

does 66^2 + 88^2 = 110^2 ?

4356 + 7744 = 12100 ?
12100 sure enough

Yes, correct! The side lengths 66 in, 88 in, and 110 in satisfy the Pythagorean theorem and can form a right triangle.
