Question from Htet, a student: I have a math dictionary to complete by February 13, 2008, Wednesday, and I need to know what a real life example of a decagon can be. I need help on this! |
Hi,
I found a couple of examples.
There are coins in the shape of a regular decagon.
There is a quasicrystal composed of overlapping decagonal clusters.
Wikipedia has an umbrella but most of the umbrellas I could find are octagons.
I hope this helps,
Penny
