Study for your Unit 4 Circles Test which will be on Tuesday, 10/30. Please finish the ENTIRE Practice Test.  We already reviewed #1 - 7 in class on Friday. I will be staying after school on Monday for anyone who needs tutoring.  There will also be tutoring on Tuesday and Thursday.  Below are the answers to the Unit 4 Circles Practice Test.  Tomorrow, I will post videos explaining all of the problems.  Be sure to review all of your formulas for solving arcs, angles & segments since those 8 formulas are not on your formula sheet.  If you need to review the constructions we did in class on Friday, go to mathopenref.com and click on "Constructions Table of contents".  The 3 constructions we covered on Friday were:
- under the "Circles, Tangent" heading, Tangent to a circle through an external point
- under the "Triangle Centers and Circles" heading, Incircle (inscribed circle) of a triangle
- also under the "Triangle Centers and Circles" heading, Circumcircle (circumscribed circle) of a triangle
