Dividing a Circle into Seven Equal Areas (visual proof)

This is a short, animated proof showing how to decompose a circle into seven pieces each with the same area. This process can be done using ruler and compass constructions, unlike the process of constructing the regular heptagon. #manim​ #mathshorts​ #mathvideo​ #math​ #geometry #mtbos​ #animation​ #theorem​​​ #visualproof​ #proof​ #iteachmath #circle #mathematics #rulerandcompass #construction #pizza

Perhaps this should be titled "The Best Way to Cut Pizza into 7 pieces" based on the comments in this video :)

There were also a number of comments asking about how to divide a line into seven equal lengths, so I have created a short, wordless animation showing that procedure if you're interested:    • Dividing a Line into Seven Equal Segm...  

This animation is based on a visual proof from Roger Nelsen's and Claudi Alsina's wonderful book "Icons of Mathematics" (Chapter 14.1 on page 76). You can find the book and other information about it at the links below
