Answer 1

A regular pentagon can be rotated around its center and still look the same! There are five different rotations: 72 degrees, 144 degrees, 216 degrees, 288 degrees, and 360 degrees (which brings it back to the start). Each of these rotations shows that a pentagon has special symmetry that keeps it looking just like itself!
