I have a great list that might help you learn some octagon facts!
1. Umbrellas are in the shape of an octagon.
2. As a symbol, octagons symbolize regeneration, infinity, rebirth, and transitions.
3. Octagons are hard to draw...You can find Octagons anywhere if you just look... just kidding only around stop signs. Lol
4. Octagons have eight angles and eight sides.
5. Did you know that you can draw an octagon with just a compass and ruler.
There ya go!
