Bisect an Angle

Start with angle PQR that we will bisect.

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.

Without changing the compass width, draw an arc across each leg of the angle.

Place the compass on the point where one arc crosses a leg and draw an arc in the interior of the angle.

Without changing the compass setting repeat for the other leg so that the two arcs cross.

Using a straightedge or ruler, draw a line from the vertex to the point where the arcs cross

Label the points.
