Suggested Activities

* Each interior angle of a regular dodecagon measures 150 degrees. Students could find the sum of all the interior angles in a dodecagon.

   (150 x 12 = 1800 degrees) 

* Here are printables of dodecagon tessellations  (and other polygon templates plus dot paper and grid paper templates) that students might enjoy. Click on the link below.
