How do you divide a circle in equal pieces?

Answer 1

Starting at one point of the circle, draw a straight line through the center of the circle to the other side. This line is called a diameter. It will divide the circle into 2 equal pieces.

Now, if you want to divide the circle into any number N of equal pieces, follow these steps in order

1. divide the diameter into N equal segments,
2. from one endpoint of the diameter, draw half circles towards every endpoint of the equal segments,
3. flip the circle,
4. from the other endpoint of the diameter, draw again half circles towards every endpoint of the equal segment (but now filling the other side of the circle).

The resulting parts of the circle have equal area.
