jimthompson5910 (jim_thompson5910):
yep, so it's a nonagon since it has 9 sides
if it had 7 sides, it would be a heptagon

its only regular if ALL sides are equal to each other, is that the case here?
OpenStudy (anonymous):
ohhh so if all the sides are equal its regualr and if the sides are not its irregualr ? correct in this case its irregualr rite ?
jimthompson5910 (jim_thompson5910):
yes, you can't measure exactly, but by the looks of things the bottom side is a bit longer than one of the top sides
so that makes it irregular
