(A comparison between straight edge and compass constructions and origami)
In high school geometry students examine the types of geometrical operations that can be performed by using only a straight edge and a compass (SE&C). One learns how to draw a line connecting two points, how to draw circles, how to bisect angles, how to draw perpendicular lines, etc. In fact, you may remember that all SE&C constructions are a sequence of steps, each of which is one of the following:
Given two points we can draw a line connecting them.
