Instructional Ideas
- Use the lesson to introduce the case where secant lines intersect inside a circle
Classroom Considerations
- The particular case in question—secant lines that meet inside a circle—is sometimes referred to as intersecting chords, rather than intersecting secant lines
- The lesson refers back to previous lessons on inscribed angles
Pros
- Lesson notes indicate where to look for mathematical practices
- Teacher resource provides a set of questions that will guide learning
Cons
- Discussion includes an activity that is similar to a previous one
