Create octagons. An octagon is a polygon with eight equal sides and eight equal angles. Octagons may be regular, meaning that all sides are of equal length and all angles are equal to one another, or irregular, meaning the lengths of the sides and the angles between them may differ. Regular octagons are found in nature, such as the honeycomb made by bees. Constructing both regular and irregular octagons is a straightforward process that can be accomplished with a ruler, a pencil, and a compass.
Octagons have a number of uses, in both regular and irregular forms. Regular octagons are often used in architecture, as they can be tiled to create a variety of visually appealing patterns. Irregular octagons are often used in engineering, as they can be used to create structures that are strong and lightweight. Octagons are also used in a variety of other applications, such as art, design, and manufacturing.
In order to make an octagon, you will need to follow these steps:
- Draw a circle. This will form the outer boundary of your octagon.
- Divide the circle into eight equal parts. You can do this by using a protractor to measure out eight equal angles around the circle, or by using a compass to divide the circle into eight equal parts.
- Connect the eight points that you have marked on the circle. This will create your octagon.
If you want to make an irregular octagon, you will need to follow the same steps, but you will not need to divide the circle into eight equal parts. Instead, you can simply connect the eight points that you have marked on the circle in any way that you like.
1. Regular
