Trigonometry Practice Tables

Trigonometry can be very difficult to get a hang of, and that's why it's so important to practice. We use a handy table to present several problems at once, and every column is a single triangle. You get some values to start with. Use those values to calculate and fill out the unknowns.

Basic Right Triangle

The following triangles are all in the form of the basic 90° right triangle where side a is smaller than side b and c is the hypotenuse. The angle is opposite side a and smaller than angle .
