Day 103: Octagonal Area

IMAG1164

One of the problems that’s been on offer of late in my Geometry class has been finding the area of a regular octagon with side length s. One of my student’s diagrams always come out so cool looking. 🙂

Another student is editing a video he made of his solution to the problem. I’ll post a link to it when he finishes it.
