Euclidean construction

Quick Reference

A construction of a geometrical figure with only compasses and a straight edge, which cannot be used for measuring lengths. For example, an equilateral triangle can be constructed by drawing a line segment with the straight edge, positioning the point of the compasses at one end of the segment and drawing an arc of the circle with the same radius as the segment, and doing the same from the other end. Where the two arcs meet is the third vertex of the equilateral triangle.
