| Start with angle PQR that we will bisect. |
 |
| 1. Place the compass point on the angle's vertex Q. |
 |
| 2. Adjust the compass to a medium wide setting. The exact width is not important. |
 |
| 3. Without changing the compass width, draw an arc across each leg of the angle. |
 |
| 4. The compass width can be changed here if desired. Recommended: leave it the same. |
 |
| 5. Place the compass on the point where one arc crosses a leg and draw an arc in the
interior of the angle. |
 |
| 6. Without changing the compass setting repeat for the other leg so that the two arcs cross. |
 |
| 7. Using a straightedge or ruler, draw a line from the vertex to the point where the arcs cross |
 |
| Done. This is the bisector of the angle ∠PQR. |
