**MathMate**, Monday, April 11, 2011 at 3:28pmRecall that the exterior angles of a

*regular*polygon add up to 360°.

So for a dodecagon (12 sides), the exterior angle is 360/12=30°.

Two dodecagons back to back will give 2*30=60° left over.

The number of sides of the regular polygon that will fit the bill

=360/60= ?
