The three primary Trigonometric Ratios are Sine, Cosine, and Tangent. As we learned previously, triangles with the same angle measures have proportional sides.

A trigonometric ratio is a ratio of the lengths of two sides of a right triangle. The most common ratios are sine (sin), cosine (cos), and tangent (tan).
