Day 35 of 101 DoCC was prompted by a student asking if the Spiral of Theodorus is the net of a shape. After work, I programmed this for them. It was a fun exercise to find the coordinates for this. I had to double check myself when I was done to make sure it really was as simple as adding previous angles. I flopped the first couple of times with far too complex methods before seeing it on my graph paper. I found this link when I was checking of a great Geogebra version.
