Question:
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?


Replies:
Corinne,

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.
