|After doing this||Your work should look like this|
|1. Draw a line segment which will become one side of the angle. (Skip this step if you are given this line.) The exact length is not important. Label it PQ. P will be the angle's vertex.|
|2. Set the compasses on P, and set its width to any convenient setting.|
|3. Draw an arc across PQ and up over above the point P. Label the point where it crosses PQ as point S.|
|4. Without changing the compasses' width, move the compasses to the point S. Draw a broad arc that crosses the first one and goes well to the right. Label the point where the two arcs cross as point T.|
|5. Without changing the compasses' width, move the compasses to the point T, and draw an arc across the previous arc, creating point R.|
|6. Draw a line from P to R.|
|Done. The angle QPR has a measure of 30°|
