Dividing Circle in Thirds With Parallels
One of two million questions of my 12-year old son is, how
to part a circle (Kreis) in 3 parts using parallel lines. I am a
Swiss mom without an understanding either in geometry nor English.
Could you please help me?
Your question does not require that the three parts be equal. It also
does not require that the three parts be "pie-shaped". Consider an
arrangement with a center piece and two side pieces. This could be
achieved with two parallel lines.
