The unit circle is an essential math concept that every student needs to understand. It sets the foundation for trigonometry, geometry, projectile motion, sine, cosine, tangent, and countless instances of applied math. When learning about the this important concept for the first time, it may be useful to have a unit circle chart on hand as a reference sheet.
Below you will find five printable unit circle worksheets. The first sheet includes all the radians, degrees, and tangents. The second printable is a blank unit circle worksheet. Fill in the unit circle to test your knowledge. The third sheet contains just the unit circle radians. The fourth diagram has just the unit circle degrees. The final chart features tangents.
