Which of the choices shown are the lengths of the sides of a right triangle

A) 1, 1, 2 B) 5, 6, 12 C) 3, 5, 8 D) 10, 24, 26

D because, 10 + 24 greater than 26

You need take the first and the second number add together must be greater the last one.

10,24,26

10+24 = 34

34>26

Option D because according to puthogrean theorem adding the two shortest sides squared should give you the longest side (hypotenuse) squared. So 10^2 plus 24^2 is 676 which is 26^2
