Sketch each of the following angles in standard position. Subtract 360 or 180 which ever is closer from the angle if θ is in degrees. Subtract π or 2π which ever is closer from the angle if θ is in radians.

About this resourceThis document contains 24 tiles that test knowledge of finding reference angles in degrees and in radians. These two worksheets practice graphing angles in standard form finding a positive and negative coterminal angle and finding reference angles in both degrees and radiansThese are ready to print or to assign as an online Easel Activity. If θ is already between these values the reference angle is θ.

360 degrees θ Reference angle. The digital version is ready-to-use but you can edit the in. Fill in the missing parts of the table.

Fill in every angle measure in degrees radians and give the coordinates of the point on the unit circle. I use an angle in degrees because students understand degrees better than radians immediately recognizing that we have gone past a full rotation. 1 326 2 530 3 215 4 84 5 215 6 255 7 660 8 255 9 172 10 700 11 340 12 540 13 495 14 315 15 210 Find the measure of each angle.
