How to Divide a Circle

Step-by-Step Guide

1. 1

   Step 1: Create a circle.

   With the Join Path tool in Pathfinder, join the angle at all three sides. ,, Select both your new shapes and use the Intersect tool in the Pathfinder.
   
   With your newly created wedge, use the rotate tool and rotate a copy of the wedge 72 degrees. , Do the rotation-and-copy process with Object, then Transform Again. , You can repeat these steps for different division, merely by using different angles.
   
   Divide 360 by how many parts you would like, and that number will be the size of your angle. 360 represents the full angle of a circle. ie.
   
   Four equal parts: 360º ÷ 4 = 90º
