Polygons

We can draw regular polygons.

Our Simple Square

We can draw a square four sides, equal length, right angles with a repeat that looks quite a lot like that description.

rpt 4 [ fd 5 rt 90 ]

A Triangle

To change the shape, we must change the angle that is turned at the corners (or vertices). It is the outside angle we are turning.

For a triangle, this is 120 degrees.

rpt 3 [ fd 5 rt 120 ]

Any Regular Polygon

You should be able to work out how to draw any regular polygon.
