See the picture below:

#### Work Step by Step

First, we have to draw a right angle with a vertex of A. Then, we have to draw the angle bisector.
1. By using a compass mark an arc with the center of A to intersect the two sides of line . Now with those two points as centers, mark off two arcs with equal radii to intersect in point R. Connect this point with A to get the right angle.
2.By using a compass mark an arc to intersect the sides of ∠RAO. Now with those two points as centers, mark off two arcs with equal radii to intersect at a point. Connect this point with R to get the angle bisector.
