What is the relationship between the angles and sides in a right triangle?

Back

In a right triangle, the angles are related to the sides through trigonometric ratios (sine, cosine, tangent). Each angle corresponds to a specific ratio of the lengths of the sides.

How do you determine which trigonometric ratio to use for a given problem?

Back

To determine which trigonometric ratio to use, identify the known sides and the angle in question. Use sine if you have the opposite side and hypotenuse, cosine for adjacent and hypotenuse, and tangent for opposite and adjacent.
