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° |
