Equal areas of a circle gives nice art

CTK Insights has an interesting post Dividing circular area into equal parts using a pair of compasses and a ruler, complete with proof. [That post is no longer available.]

I applied the process given and divided my circle into 5 equal parts (the semi-circles have centres on the diameter of the large circle, and each semi-circle is a multiple of 1/5 of the large diameter).

Here it is, using squareCircleZ colors: :-)

    I’m always on the look-out for design activities to use with Year 10 after their exams. I made a simple template for making this design:

    Thanks for pointing out this nice design.
