Draw the angle carefully and link it to the origin with the use of a straight line.

In that quadrant, make a 30-degree angle for your unit circle.

Start in the first quadrant on a graph.

Here are some tips you can use to make your own unit or radian circle chart: They did this so that all the angles would fit into the whole unit circle. The angles connected to one another have trig functions which are also connected, if not the same. But there’s more to these different names. You may think that the different angle names are just pointless and confusing. In fact, the same 60-degree angle would have a lot of different names in both radians and degrees. These angles are the 420-degree angle and the -300-angle. If you have an angle that measures 60-degrees, it would have the same terminal side as the other angles. Getting confused yet? Let’s clarify with an example. Then you can get positive and negative values of the same basic angle. You can do this when you add or subtract 360-degrees during the rotation.ĭo these before you settle on the terminal side of the angle.

When you perform a complete rotation of the circle, you can get endless angle measures.

However, there are more ways you can name angles. This is because their terminal sides are the same. In order to get these values, you need to measure the angles in a clockwise direction.įor instance, a 30-degree angle is the same as a -330-degree angle. In fact, a lot of basic angles have negative values and multiples of themselves. Aside from positive angles, unit or radian circle charts also show negative angles.
