In this unit, you studied a handful of circle
theorems. However, there are other circle
theorems not covered in this unit or course.
Do some research online or in textbooks to
uncover a circle theorem (or more than one)
that wasn't presented in this unit. Describe it
in detail. Then write either a two-column
proof or a paragraph proof for the theorem.
Does the theorem that you proved relate to
theorems that you previously studied? If so,
how? Were you able to apply some theorems
that you proved earlier to your newfound
theorem? Explain. How might your theorem
be used in a real-world application
