Trigonometry is a study of math whose origins date back to the ancient Egyptians. The principles of trigonometry deal mostly with the sides, angles and functions of triangles. The most common triangle that is used in trigonometry is the right triangle, which is the basis for the famous Pythagorean Theorem, in which the square of both sides of a right triangle are equal to the square of its longest side or hypotenuse
