The octagon is a basic polygonal shape consisting of eight sides. A regular octagon consists of eight equal sides and angles. The stop sign is a common and recognisable regular octagon. You can draw a regular octagon on graph paper according to a straightforward step-by-step process.

You can also draw an irregular octagon in one simple step.

Choose a centre point for the octagon at an intersection on the grid. It should be somewhere near the centre of the area in which you want to draw the octagon.

• The octagon is a basic polygonal shape consisting of eight sides.
• You can also draw an irregular octagon in one simple step.

Draw a circle around the central point using the compass. The radius is the distance from the centre of a circle to its edge. For ease and precision, choose a radius length equal to a whole number of grid boxes. For example, you can choose a length of four grid boxes for your radius, which will create a circle whose diameter is eight.

Draw a vertical diameter and a horizontal diameter with the ruler. A diameter is a straight line connecting two opposite points on a circle that passes through the centre point. This will create a cross shape and will mark four corners of the regular octagon.

• Draw a circle around the central point using the compass.

Draw two more diameters that bisect, or cut in half, the angles created by the first two. This will create eight 45-degree angles.
