What is the least number of degrees you could rotate a regular pentagon (5 equal side lengths) around its center so that it appe
Leya [2.2K]

Answer:

Well, I'm not the smartest person, nor do I exactly know what you mean, but I have a wild guess that the least you could rotate it is 100 degrees.

I hope this helps you, like I said, I don't exactly know what you are talking about, I am not studying that sort of thing yet.
