Unit 10: Circles

This Unit is about Central and Inscribed Angles, Areas of Sectors, and Arc Measure and Length.




 

















The picture above is of a circle that has a central angle, an inscribed angle, and a tangent angle.


Most of you won't read this:
A good study habit would be to make a test for yourself over the problems that challenged you in the notes. After you take your self-made test, grade it using the solutions from the notes. Get comfortable with being wrong from time to time and learn from your mistakes. Lastly, study sessions do not have to be up to an hour at a time. You could study for 10 minutes a day 3 times per day.
