This is pretty cool you can actually trisect a line with just a compass and a straight edge. It was in an old book I had, I mean like really old.

You just swing two arcs up to form the large triangle, then bisect the sides and you have the center point, then just swing two arcs the length of the midpoint of the height of the will be little triangle and get a thirty degree side of the smaller triangle. It is pretty cool, all you need is a compass and a straight edge or even a string, and of course a marking device.

I have some others for making circles inside of circles pretty cool stuff.

Sincerely,
