What is the definition of a central angle?

• An angle with its vertex at the center of the circle

• An angle formed by two tangents to the circle

• An angle with its vertex outside the circle

• An angle with its vertex on the circle

What is the relationship between a central angle and its intercepted arc?

• There is no relationship between the central angle and the intercepted arc

• The central angle is half the measure of the intercepted arc

• The central angle is twice the measure of the intercepted arc

• The central angle and the intercepted arc have the same measure
