13 lines passing through the center will create 26 pie-shaped parts. Now if you need them to be equal parts, I'm not sure about that one.
Not everyone knows ?
You just divide the circles into 4 parts
have have to divide them
You can cut a round cake into eight parts with three cuts, but you can't cut a circle into eight parts with three straight lines.
dragons no wait... ELVES
Draw two diameter lines, then draw a circle inside the circle.
Cut/draw 21 lines from the center out.

Thet are straight lines which divide an angle into two equal parts.
draw a circle and cross 12 lines through it like a pizza moron
Yes you can, but you have to use zig zag lines. Using straight lines there are only four ways to divide a square into two equal parts (along the lines of symmetry).
You can't. However, you can divide it into seven, like so: Make the lines make a triangle in the middle of the circle, rather than making them meet at the centre.
Divide each side into three equal parts. Then join the division marks on opposite sides with straight lines parallel to the other side(s).
step 1: make a circle with a compass step 2: divide the circle into 4 equal parts step 3: draw curved lines
A chord is a straight line drawn through a circle which divides the circle into two parts. The line can be drawn anywhere in the circle EXCEPT the center where it becomes the diameter.
