Question

Ok but fr help.. Assuming only the lengths of the sides of a triangle are given, how can you determine if the triangle has a right angle?

Answer 1

If you take the 2 smallest sides and put it in the pythagreon theorem to get the other side length.

Explanation:

So if you have a triangle with side lengths, 3, 4, and 5, you can use the exact equation below.

`{3}^(2) + {4}^(2) = {5}^(2)`

Because this is true, then the triangle does have a right angle.
