square of largest side.

If square of largest side is equal to the sum of squares of smaller two sides, the triangle is right angled.

Here as

**Note** - if square of largest side is greater than the sum of squares of smaller two sides, the triangle is obtuse angled and if square of largest side is less than the sum of squares of smaller two sides, the triangle is acute angled.
