A heptagon is a shape or a polygon which has 7 sides, and with a total internal angle measure of 900.

Heptagon has 7 sides while a hectagon had 100 sides. That sounds mental ! πŸ™‹πŸ€“ Hahaha..

Getting my blunt on and realizing just how nerdy I must be ... But in all seriousness, math is great because no matter how high I be ...math is always gonna be the same.; It don't lie and never changes from day to day because of the weather , mood or gf having her period. 
Thanks Math. I love you.
