Features of a Circle
Instructions
In the diagram below, find as many missing angles, arcs and line segment measurements as you can. Be sure to use the Theorem we learned in class including: Central Angle Theorem, Inscribed Angle Theorem, Radius-Chord Theorem, and what you know about the measurement of circles.

What is the measure of
4
What is the measure of
5
What two line segments, that are NOT radii can you say are congruent? Why?
6
What is the measure of
7
Finish the statement: is a(n) {equilateral, isosceles, scalene} triangle. How do you know?
8
What is the measure of arc AC?

What is the measure of
10
True or False? If not, why not. If so what congruence theorem can you use to prove this? (SSS, ASA, AAS, etc)
