Question

Does 36,84,91 make a right triangle?

Answer 1

No, it will not make a right triangle.

Explanation:

Use the Pythagorean Theorem.

`a^2+b^2=c^2`

91 is the biggest number, so it would be 'c'. 36 and 84 will be 'a' and 'b'.

`36^2+84^2=91^2\\\\1296+7056=8281\\\\\boxed{8352\\eq 8281}`

The sides will not form a right triangle, since the final result is a contradiction.

Hope this helps.
