Making geometric solids...One of the things we do on occasion in the woodshop is make geometric solids for the study of geometry. At left is a worksheet showing the method used for determining cut angles for making a pyramidal nonagon, or what could be called a nine sided pyramid. Below is the completed pyramid after being cut upside down on the bandsaw and liberated from the surrounding matrix. This project was done by Kyle Hunnicutt and Zach Gates in spring, 2005.
