How to trisect a line? Using an Unmarked Ruler and Compass, Method 3

Using only a compass and an unmarked straightedge to trisect a line segment.
How to draw? It's super simple, step by step!
1.Draw any line segment AB.
2.With A and B as centers, draw two circles with radii equal to AB.
3.With the intersection of the two circles as the center, draw a circle with a radius equal to AB.
4.Mark the intersection points as C and D.
5.Draw a line passing through points B and C, intersecting circle C at point E.
6.Draw a line passing through points E and D, intersecting AB at point F.
7.Use a compass with F as the center and AF as the radius to draw a circle intersecting AB at point G.
8.Now, AF = FG = GB.
Thanks for watching!

    Again, you should always assume that the compass collapses whenever raised from the surface. At least that's the way they taught it in HS in the early 1970s.
