We know theorems about circles—now what? Class members prove a theorem, with half the class taking the case where a point is inside the circle and half the class taking the case where a point is outside the circle. The lesson plan then provides exercises to find an unknown angle by applying theorems about circles.

Instructional Ideas
- Briefly review theorems before beginning lesson
Classroom Considerations
- Pupils need to be familiar with all previously learned theorems about circles
- The four exercise problems are likely to take more than the allotted 13 minutes, especially if the class needs to be divided into groups
- The sixth installment of a 23-part module
Pros
- Teacher resource provides not just answers but explanations as well
- Problems include application of the Inscribed Angle Theorem in different situations (such as chords extending outside the circle)
Cons
- None
