To divide a circle into thirteenths, divide it into thirteen equal portions, or pieces.
circle is 2d so, just fold it 15!

You divide 360 degrees by eight (there are 360 degrees in a circle) so each section would be 45 degrees.
draw a + inside it, touching the outside of the circle-cut it into Quaters.
To divide a circle into thirteenths, divide it into thirteen equal portions, or pieces.
A diameter is a line connecting any two points in a circle that passes through the centre of a circle. You can draw 1 diameter and divide the circle in half. You can draw 2 and divide it into 4 pieces or draw an infinite amount and divide it into infinite pieces.
From the center of the circle, draw like a cross from there.

Use a protractor and divide it into 36 degree wedges.
By marking out 10 arcs of 36 degrees around its circumference and joining them to the centre of the circle.
Mark out 10 by 36 degree arcs around its circumference and then join them up to the center of the circle.
Divide the circle's circumference into six 60 degree angles and join the angles to its centre then cut it into 6 equal pieces.
Think about a circle. If you divide it into six equal parts, each part is 1/6 of the circle. Now think about a circle that is identical to the first. If you divide that one into eight equal parts, each part is 1/8 of the circle. If you compare the two divided circles, you will see that the 1/8 pieces must be smaller than the 1/6 pieces, because eight pieces are filling the same space as six pieces. Draw this out on paper to prove this to yourself if need be.
If the shape has high symmetry like a circle then it's easy to do. If not, measure the area, divide it by N (the number of pieces you want) and chop off that quanitity (N-1) times and, with the bit left over you will have N equal pieces.

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 orderdivide the diameter into N equal segments,from one endpoint of the diameter, draw half circles towards every endpoint of the equal segments,flip the circle,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.
