## 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

## 3

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?

## 9

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)
