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.
1
What is the measure of arc BC?
2
What is the measure of [math]\angle EOA?[/math]
3
What is the measure of [math]\angle ODB?[/math]
4
What is the measure of [math]\angle BOE?[/math]
5
What two line segments, that are NOT radii can you say are congruent? Why?
6
What is the measure of [math]\angle AOC?[/math]
7
Finish the statement: [br][math]\Delta AOC[/math] is a(n) {equilateral, isosceles, scalene} triangle. How do you know?
8
What is the measure of arc AC?
9
What is the measure of [math]\angle OCF?[/math]
10
True or False?[br][math]\Delta BOD\cong\Delta AOD[/math][br][br]If not, why not. If so what congruence theorem can you use to prove this? (SSS, ASA, AAS, etc)
