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

A.
42 in, 63 in, 70 in
B.
42 in, 56 in, 70 in
C.
35 in, 56 in, 70 in
D.
42 in, 56 in, 84 in

wrong

The correct answer is:

B. 42 in, 56 in, 70 in

These measurements satisfy the Pythagorean theorem, a^2 + b^2 = c^2, where a and b are the two shorter sides of the triangle, and c is the longest side (the hypotenuse).

C. 35 in, 56 in, 70 in
