If a regular polygon has 12 sides, each exterior angle is...

10

The interior angle sum formula depends on the number of sides, not regularity. True or False?

A hexagon’s interior angles sum to (6-2)*180 = 720 degrees.

Interior angle = (n-2)*180/n = 6*180/8 = 135°.

Exterior angle = 360/n = 360/5 = 72°.

Around the polygon, exterior angles total 360°.

Interior angles >180° indicate a concave polygon.

Sum = (4-2)*180 = 360°.

Angle = (n-2)*180/n = 7*180/9 = 140°.

Each hexagon has interior angle 120°, so 3 meet to make 360°.

Exterior angle = 360/12 = 30°.

The sum depends only on the number of sides: (n-2)*180°.
