A triangle has side lengths of 7, 24, and 25. Is the triangle right, acute, or obtuse?

I think that it's an obtuse triangle.

If the squares of the shorter sides added together are:

Equal to the square of the longest side - the triangle is right angled

Less than the square of the longest side - the triangle is obtuse angled

More than the square of the longest side - the triangle is acute angled

This example would be right, which comes from the Pythagoras theorem
