If it's a regular 28-agon then each interior angle is: (26*180)/28 = 167.'142857' degrees recurring decimals 0.'142857'

A regular 12-sided polygon is called a dodecagon - from the Greek dodeka, meaning 12, and gonus, meaning angle.
Ext.Angle = 360n (no. of sides_ Int.Angle = 180 - Ext.Angle. Substituting. Int.Angle = 180 - 360/n Hence Int.Angle = 180 - 360/28 Int.Anglr = 180 - 12.857.... Int.Angle = 167.142.... degrees.
