Question

Describe how to construct an angle bisector with a compass and starightedge.

Answer 1

Here is how to bisect the angle B A C: Place the point of the compass on A, and swing an arc E D. Then, with D as center and D E as radius, draw an arc. Keeping the same radius and with E as center, draw an arc that will intersect the first; call that point of intersection F, and draw A F.
