## What’s the difference between a regular and irregular octagon?

There are regular (RO) and irregular octagons (IO), and their properties are as given below. 1. RO: They have eight sides. IO: They have eight sides. 2. RO: All 8 sides are equal. IO: Sides are not equal. 3. RO: It is always a convex figure. IO: The figure can be convex or concave. 4.

**Is the hypotenuse also the side of the Octagon?**

In this case, the hypotenuse is also the side of the octagon. Then you can calculate the area of the parallelogram you just made from the four right triangles, and subtract it from the area of the big square. On top of these, you can get even more creative.

### Where does the word Octagon come from in Greek?

If we look at the origin of the word ” Octagon ” it comes from the Greek meaning ” eight angles “. The result of this is a polygon composed of eight vertices joined by eight straight lines. The eight sides are a necessary consequence of having eight angles.
