The authors believe that this textbook would be appropriate for a 3-hour, 4-hour, or 5-hour
course. Some instructors may choose to include all or part of Appendix A (Algebra Review)
due to their students’ background in algebra. There may also be a desire to include The
Introduction to Logic, found at our website, as a portion of the course requirement. Inclusion
of some laboratory work with a geometry package such as Geometry Sketchpad is an option
for course work.

Section 8.5 More Area Relationships in the Circle
