Math CentralQuandaries & Queries


Question from Ella, a student:

they give you a simple straight line and ask you to construct an angle of 30 degrees at one end of the line using only a ruler and a compass?

Hi Ella,

First construct a 60 degree angle at one end of the line and then bisect it. Do you know how to construct a 60 degree angle?
