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