Without loss of generality let the side length of the triangle be 1. Connect these two points to the center point and you have the circle divided into three. Dividing into thirds by geometry.

Colour triangle AEH blue. More lines are needed to divide it into four quarters. Divide a triangle into 3 equal parts.

We start with a given line segment and divide it into any number of equal parts. The minimum length is to divide the triangle by joining the centre to the midpoint of each side with straight lines. The white sector has area 12π2 – θ.

When a triangle is an equilateral triangle or a triangle with sides of equal length then the perpendicular bisectors can be used in a neat way to divide the triangle into three equal parts. The area of the black triangle is then 12c1-c² the hypotenuse is a radius of the circle and so has length 1.

More lines are needed to divide it into four quarters. This will give you two points. If a triangle ABC is given and a random point P on the triangle is selected construct two lines through P to divide the triangle into three regions with equal area.

Using a compass and straightedge we do this without measuring the line. Make sure it is level height needs to be uniform. This is fold EC.

How to divide a line segment into equal parts with compass and straightedge or ruler. Take your ruler and draw a perpendicular line from this point to the outside diameter of the circle. The two possibilities can be seen below.

These six triangles actually consist of three pairs of equal triangles formed by the division of three triangles formed from the centroid and three pairs of vertices by the part of median from vertex G to the base. Try fashioning an equilateral all 3 sides of the same lenght triangle with the dough. We present a proof of this statement.

The blue triangle has sides twice as long as the red and yellow ones. Fold the square in half a book fold B to E.
