Question

Do the following side lengths form a right triangle?

51, 68, 85

Answer 1

Answer: Yes

Explanation:

If these lengths were to form a right triangle, then 51 and 68 would be the legs and 85 would be the hypotenuse.

`51^2 +68^2 =7225\\\\85^2 =7225\\\\\therefore 51^2 +68^2 =85^2`

So, the side lengths form a right triangle.
