The converse of the Pythagoras Theorem is also valid. The Pythagorean converse theorem can help us in classifying triangles. If the square of the length of the longest side of a triangle is equal to the sum of squares of the lengths of the other two sides, then the triangle is a right triangle.
You can classify triangles by the measures of their angles. An acute triangle has only acute angles. A right triangle has one right angle. An obtuse triangle has one obtuse angle. To classify the triangle below by its angles, you first need to find the measure of all the angles. The sum of the angles of a triangle is 180°.
The algorithm of this right triangle calculator uses the Pythagorean theorem to calculate the hypotenuse or one of the other two sides, as well as the Heron formula to find the area, and the standard triangle perimeter formula as described below. Moreover it allows specifying angles either in grades or radians for a more flexibility.

ASA (angle side angle) = If two angles and the side in between are congruent to the corresponding parts of another triangle, the triangles are congruent. AAS (angle angle side) = If two angles and the non-included side of one triangle are congruent to the corresponding parts of another triangle, the triangles are congruent.
