Finding Tangent of an Angle
More Lessons for Trigonometry
Videos, worksheets, games and activities to help students learn how to find the tangent of an angle in a right triangle using sohcahtoa.
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.
