The hypotenuse is the longest side of the triangle and is labeled as. The side of the triangle that is opposite of the angle and connects the two legs is known as the hypotenuse. The legs of the triangle form the angle and they are labeled and.

It is a special triangle and needs to be labeled accordingly. A right triangle is a triangle that has one angle. Let's first discuss right triangles in a general sense. We can do this by using the Pythagorean theorem. In right triangles, we can calculate the perimeter of a triangle when we are provided only two sides.

The perimeter formula is written formally in the following format: right, acute, obtuse, equilateral, isosceles, and scalene). Second, when all the side lengths are known, then the perimeter formula may be used on all types of triangles (e.g. First, we need to make sure that all the units given match one another. If we know the lengths of sides, , and, then we can simply add them together to find the perimeter of the triangle.

This method will show you how to calculate the perimeter of a triangle when all sides lengths are known.
