Tangent Ratios:

Right triangles have ratios that are used to represent their base angles. Tangent ratios, along with cosine and sine ratios, are ratios of two different sides of a right triangle. Tangent ratios are the ratio of the side opposite to the side adjacent the angle they represent. Trigonometric Ratio: Tangent

Given an angle A in a right triangle, then tan A is equal to the length of the leg that is opposite to this angle A, over the length of the leg that is adjacent to this angle A.

A mnemonic that will help you remember this ratio easily: T. O. A. TOA is a mnemonic for tangent, opposite, and adjacent.

This is a video tutorial on the Trigonometric Ratios, Sine, Cosine and Tangent. This video tutorial will help you remember the trig ratios using the acronym, sohcatoa. At the end of the video there will be some sample problems.
