C. 16 cm, 63 cm, 65 cm cannot represent the lengths of the sides of a right triangle because the sum of the squares of the two smaller sides (16^2 + 63^2) is not equal to the square of the longest side (65^2) according to the Pythagorean theorem.
3,4,5 is a well known right triangle. Note 3^2 + 4^2 = 25 = 5^2
6 , 8 , 10 is similar, just sides twice as long
YES 16^2 + 63^2 = 256 + 3969 = 4225 which is 65^2, It works !!!!!!
8^2+9^2 = 64+ 81 = 145, nope not 10^2 = 100
Once again I disagree with answered
