|After doing this||Your work should look like this|
|Start with angle PQR that we will bisect.|
|1. Place the compasses' point on the angle's vertex Q.|
|2. Adjust the compasses to a medium wide setting. The exact width is not important.|
|3. Without changing the compasses' width, draw an arc across each leg of the angle.|
|4. The compasses' width can be changed here if desired. Recommended: leave it the same.|
|5. Place the compasses on the point where one arc crosses a leg and draw an arc in the interior of the angle.|
|6. Without changing the compasses 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.|
