How Do You Divide a Circle into Eight Equal Parts?
To divide a circle into eight equal parts, divide the circle into HALF, with any diameter. Continue and fold the resulting half-circle shape in half again to give QUARTERS.
Fold again the quarters into a wedge shape (bisector).
This will give 8 equal parts, but you need to fold the paper...

DIVIDING A CIRCLE INTO 8 PARTS USING
BISECTORS:
USE BISECTORS to have 8 equal parts (2 squares). The process and result are the same, but you will NOT fold the paper sheet.
DRAW the circle with the given radius: r=8cm. Do not miss its center!
DIVIDE the circle into 2 equal parts, using one diameter: this will give you 2 HALVES.
DIVIDE again those two parts into 4 (quarters), USING BISECTORS.
And DIVIDE again those quarters into 8 equal parts (eights), drawing 2 new bisectors.
The result may look like this:
