## What is the formula for finding the perimeter of a triangle?

Remember the formula for finding the perimeter of a triangle.

For a triangle with sides a, b and c, the perimeter P is defined as: P = a + b + c.

What this formula means in simpler terms is that to find the perimeter of a triangle, you just add together the lengths of each of its 3 sides.

## How do you find the side of a triangle given two sides?

How do you find the side of a right triangle given two angles and hypotenuse? Answer: If you know two angles, then you can work out the third since all the angles sum to 180 degrees. If the sides are a, b and the hypotenuse is c (opposite angle A), and the angles are A, B and C, then Sin A = a/c, so a = cSin A.
