Inscribed and Circumscribed Polygons - Lesson 10-7
Today we learned about inscribed and circumscribed polygons. We started by defining them:

We then learned a couple of properties regarding them:

![Theorem 93 - Parallelograms inscribed in a circle](Theorem93.gif)
The following diagram should give you a "visual" of why Theorem 93 is true. Notice that when the parallelogram is no longer a rectangle, it is also no longer inscribed:
