Question: What is the measure of an inscribed angle that intercepts an arc of 80 degrees?

Options:

1. 40 degrees
2. 80 degrees
3. 160 degrees
4. 20 degrees

Correct Answer: 40 degrees

Solution:

The measure of an inscribed angle is half the measure of the intercepted arc. Therefore, it is 80 degrees / 2 = 40 degrees.
