## Bisect Angle ABC.

Steps.
1. Center your compass at B, and draw an arc that intersects both ray BA and BC at points E and F.
2. Using E and F as centers, draw two arcs with the same radii that intersect at point D. (Point D should be in the interior of ABC.)
3. Draw ray BD. Ray BD is the angle bisector.
