How many sides are there in this polygon?

OpenStudy (anonymous):

9 sides rite ?

OpenStudy (anonymous):

no my bad 10 !

jimthompson5910 (jim_thompson5910):

yep, so it's a nonagon since it has 9 sides if it had 7 sides, it would be a heptagon

jimthompson5910 (jim_thompson5910):

so it's either B or C

jimthompson5910 (jim_thompson5910):

no there's 9

OpenStudy (anonymous):

jimthompson5910 (jim_thompson5910):

OpenStudy (anonymous):

oh im srry icounted wrong....wait its regular cus its a normal shape rite ?

jimthompson5910 (jim_thompson5910):

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

OpenStudy (anonymous):
