How do you divide a circle into 8 equal parts using 3 lines?
Draw two diameters perpendicular to each other. Draw a smaller circle with the same centre such that the radius of the inner circle is 'r' and the radius of the outer circle is 'r√2.' [Or, the radius of the outer circle is R and the radius of the inner circle is R/√2.]

Can you cut a circle into 5 equal parts?
AnswerThere are 2pi radians in a full circle. If we cut a circle into 5 equal parts, each central angle will have 2pi/5 (or 72 degrees), and each arc intercepted form those central angles will be (2/5)(pi)(r). AnswerYes, you can, using just a compass and straight edge. For any given circle you construct, construct a pentagon inside it using that compass and straight edge, then use the vertices of the pentagon to divide the circle into 5 equal sectors. Use the link below to see how the construction proceeds.
