What is the measure of interior angle of a regular polygon with 7 side? Going round you turn 1/7th of a full revolution (2*pi/7) at each corner. (Or 360/7 degrees at each corner if you prefer units of degrees). The interior angle is pi minus thisâ¦ amount of turn (or 180 degrees minus this amount of turn if you prefer).
