a)Draw a line thru the center intersecting 2 points on either sides of the circle
b)Using radius of the same circle, draw 2 arcs in both intersecting points. Along with the straight line, this will cut out 4 sectors, with the rest of the circle sum to get for the 5th portion.
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.
Divide each side into three equal parts. Then join the division marks on opposite sides with straight lines parallel to the other side(s).
A circle divides a plane into three parts.
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.
