A polygon is a shape where all the sides are straight lines and all the inside angles are the same.

Drawing a Square

A square is made up of four sides and the angle the turtle will need to turn at each corner is 90o degrees.


Drawing an Equilateral Triangle

An equilateral triangle is made up three sides and the angle the turtle will need to turn at each corner is 120o degrees.


Drawing other Polygons

The table below shows how you could draw other polygons. Notice that the angle to turn is worked out by dividing 360 by the number of sides.

Shape Angle to Turn

Pentagon
72

Hexagon

You could use the penup and pendown commands to draw lots of different polygons on the same page.
