Introduction
“Construction" in Geometry means to draw shapes, angles or lines accurately.These constructions use mainly compass,straightedge (i.e. ruler) and a pencil.This is the "pure" form of geometric construction where no numbers are involved.While drawing these constructions, you need to use a sharp medium-hard lead (H to 3H).Draw construction lines extremely light and allmain lines medium to thin but dark.
