We began our unit on circles today with an introduction to some new terms as well as a review of some calculations that the students have seen before in previous math classes. Radius, circumference, area, diameter, center, secant, tangent, chord, and point of tangency were all discussed and demonstrated. Working with congruent and similar circles and concentric circles were also aspects of this unit that students were introduced to.
Homework: circle calculation worksheet #1-9 all; section 9-1; page 330; classroom exercises #1-10 all
