Work out polygon exterior angle instantly with clear inputs, formula shown and shareable results.
Walking once around any convex polygon you turn through a full revolution, so the exterior angles always total 360°. For a regular polygon each turn is therefore 360°/n.
Exterior angle
θ = 360° / n, and Σ exterior = 360° for every convex polygon
No. That is the striking part: a triangle and a 100-gon both have exterior angles totalling 360°.
n = 360° ÷ exterior angle. An exterior angle of 24° means 15 sides.
