The heptagon is the ugliest of the regular polygons. Go on, try and find an uglier one!

And don’t even get me started on heptagon’s interior angle sum, 900° ?! Even the number is not pretty. Not like the svelte 180° of the triangle or perfect 360° of the square, or the regal 1080° octagon!

900° is a kiln firing temperature for mediocre bisqueware, not a respectable angle sum.

Heptagon, just watch yourself…
