Basic Geometric Constructions: copy a line, draw an isosceles triangle & an equilateral triangle

Geometric constructions are done with a compass and a straightedge. In this video, I show how to copy a line segment, how to draw an isosceles triangle, and how to draw an equilateral triangle using those tools — or actually, the equivalent tools in a drawing software.
