In mathematics and science, a right triangle (or more generally, a trigonometric triangle) is a fundamental geometric figure. It has the properties of an angle and a length, and is the basic building block for all other geometric shapes.

The trigonometric functions are the most important functions in mathematics and physics. They are the functions of angle and angle transformation, of the sine, cosine, and tangent. The trigonometric functions are used to solve many mathematical problems, and are especially useful in trigonometry and geometry.
