Shapes are the important theme in Geometry. In geometry, the shapes that are enclosed shapes are said to be polygons. The type of polygon is divided on the basis of its sides. Octagon is a polygon which has eight sides. There are two types of octagon. They are regular octagon and irregular octagon. In this article, we shall discuss to make a regular octagon. Also we shall discuss to make irregular octagon.

Learn how to make a regular octagon:


  • Step 1: At first, make a vertical line PQ.

  • Step 2: Octagon has 135degree as its interior angle. We can use protector to mark 135° on both sides of the line PQ and mark it as R and S. Make the lines from P to R and Q to S. PR and QS are the line that has the same length of PQ.
