Square or rectangle

If exterior angles are 120 then interior angles must be 60 so you have an equilateral triangle

If the polygon has n sides, each exterior angle is 360/n degrees.The interior angle is 180 less exterior angle.

360 ________________________________________________ Sum of Interior Angles of a Polygon = 180 (n-2) Sum of Exterior Angles of a Polygon = 360 The sum of an angle and an exterior angle of a regular polygon is 360

Exterior angle regular polygon = 360° ÷ number of sides = 360° ÷ W Interior angle regular polygon = 180° - exterior angle regular polygon = 180° - (360° ÷ number of sides ) = 180° - (360° ÷ W)
