Which set of lengths are not the side lengths of a right triangle? (A-28, 45, 53) (B-13, 84, 85) (C-36, 77, 85) (D-16, 61, 65) [
nikklg [1K]
Side lengths 16, 61, and 65 are not part of a right triangle.

A right triangle's sides should follow this formula, C being the largest number:

a^{2} + b ^{2} = c^{2}

16^{2} = 256

61^{2} = 3721

65^{2} = 4225

256 + 3721 = 3977

3977  \neq 4225
