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.
Draw two diameter lines, then draw a circle inside the circle.
The three parts are:the interior of the circle, the points on the circle (points on its circumference) the outside of the circle.
Construct a circle with a 4.5 radius. The circle's circumference is 360 degrees. So mark out 3 by 120 degrees on the circumference and join them to the centre of the circle which will divide the circle into three equal parts.

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.
Draw two diameter lines, then draw a circle inside the circle.
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.
The three parts are:the interior of the circle, the points on the circle (points on its circumference) the outside of the circle.
A circle divides a plane into three parts.

A circle has 360 degrees inside it, 360/3=120. Cut the circle up so that there are three 120 degree angled wedges and you have 3 equal parts.
Using a protractor divide it into three parts, each of 120 degrees. Shade two of them
Divide each side into three equal parts. Then join the division marks on opposite sides with straight lines parallel to the other side(s).
trisect the bottom side, and draw two lines from the top vertex to the bottom.
shade in 6 then divide the next circle, square, ect.. into 10ths then shade in 3 parts.
