1. Create a circle with center at C that intersects segment AB at two different points (not A or B). 2. Create points D and E at those points of intersection. 3. Create a circle with a center at D that goes through E. 4. Create a circle with a center at E that goes through D. 5. Create Point F at the intersection below segment AB. 6. Create line CF. Line CF is perpendicular to segment AB.
