Question

Which side lengths below DO NOT produce a right triangle?

Answer 1

Answer: C

Step-by-step explanation:

The pythagorean theorem states that all right triangle side lengths can go into the equation $a^{2}$ + $b^{2}$ = $c^{2}$

All you need to do is insert the given number and see if it turns out true.

If you go through each equation, C is the only one that turns out wrong, making it not possible.

(For example, for A, (5×5) + (12×12) = 13×13. This becomes 169 = 169, which of course is true.)

Answer 2

C 3*3 = 9 6*6=36 and 36 plus 9 is 45 and 9*9 = 81 so it’s not equal and not right.
