p18**All angles in an equilateral triangle are 60 degrees. If you bisect a 60 degree angle, you get two 30 degree angles.
1. Draw a line segment AB
2. Draw circle A, radius AB
3. Draw circle B, radius AB
4. Label the point of intersection as C
5. Draw line segments AC and BC.
To bisect angle A:
1. Draw circle A, any radius
2. Label the points of intersection as D and E
3. Draw circle D, radius DE
4. Draw circle E, radius DE
5. Label the point of intersection as F
6. Draw ray AF
