Any shape with one number

Draw a regular polygon using the variable sides: the turtle should turn 360 / sides degrees each time. Try changing sides to see other shapes.

Learn

Turn a corner and you turn part of a full circle (360 degrees). A shape with 5 sides turns 360 ÷ 5 = 72 degrees at each corner, a hexagon turns 60. So one variable, sides, can control the whole shape.

Your task

Draw a regular polygon using the variable sides: the turtle should turn 360 / sides degrees each time. Try changing sides to see other shapes.

Stretch challenge
