Multiple Choice
Which of the following best represents line GH?
4
Multiple Choice
Which of the following best represents line BK?
5
Multiple Select
Which of the following best represents the point of tangency in circle J?
6
What is a Central Angle?
A central angle is an angle whose vertex is at the center of the circle and is formed by two radii.

Ways to label angles
By the Vertex:
By the points: (Vertex should always be in the middle of two points)
If angles are numbers then can be labeled by number. Example:
9
Multiple Select
Choose the correct way(s) to label the angle.
10
Ways of Labeling Arcs
Use the endpoints of the arc:
CB or BC would be the blue arc
CDB or BDC would be the red arc (use points in-between endpoints to indicate which direction to go in)
Arc CBD (Start at C, go to B then go to D)
11
Multiple Select
Correctly choose the correct names for the central angle and its intercepted arc
12
Multiple Select
Choose the correct way to label the pink arc
13
Labeling arcs and angles
Labeling angles stays the same as before
Labeling the arc stays the same
The intercepted arc corresponds to the endpoints of the angle. Example: The intercepted arc of is Arc GE
14
Multiple Select
Check the boxes that have the correct label for the red arc.
15
Labeling Inscribed Angles and Arcs
Labeling Inscribed Angles is the same as normal angles
Labeling Arcs is the same.
Example: the inscribed angle is and the intercepted arc would be the endpoints of the angle EG
