Unit Circle Quiz

Yes, completely free. No signup or email required. Take it here or make your own version later to customize for your math class.

Exact sine, cosine, and tangent values at standard angles from 0° to 330°, degree/radian conversions, reference angles, quadrant signs, coordinates, and unit-circle definitions.

Use the unit circle centered at (0, 0) with radius 1. Positive angles are measured counterclockwise from the positive x-axis. The ° symbol means degrees; conversion questions explicitly say radians. Give exact values, such as 1/2 or √3/2, rather than rounded decimals.

This quiz is designed for precalculus and trigonometry students, typically grades 10-12 or college-level math.

Each correct answer earns 1 point with instant feedback and a mathematical explanation.
