The Importance of Ratios in Trigonometry
The trigonometric functions are based on properties of right triangles. Right triangles have one 90-degree angle on the interior, two shorter sides and a longer, slanted side called the "hypotenuse." In trigonometry, the concern is with an unknown angle....
Trigonometry is most simply associated with planar right-angle triangles (each of
.... These ratios are given by the following trigonometric functions of the known ...
Demonstrates how to use trig ratios to do simple solving of triangles.

Trigonometric Ratios. If one of the angles of a triangle is 90º (a right angle), the
triangle is called a right angled triangle. We indicate the 90º (right) angle by ...
Trigonometry (from Greek trigonon "triangle" + metron "measure") ... Trigonometry

The trig ratios can be used to find lots of information, and one of their main
purposes is to help solve triangles. To solve a triangle means to find the length of
The six trigonometric ratios relate the sides of a right triangle to its angles.
Specifically, they are ratios of two sides of a right triangle and a related angle.
