Broken plates

From Holt's "Geometry" textbook (the old one)

All these trips to ancient sites put me in the mood to try out a new project with my geometry students. I gave them a "plate shard" (pictured below), and they had to use geometric constructions to find and draw the correct size of the plate (perpendicular bisectors and the circumcenter, in case you don't remember). Next, they had to imagine what was on the plate based on the fragment I gave them. The fragment (below) was drawn by one of my students at my request. Alas, I can not draw worth a darn. The results were outstanding. See below!
