- Summary
In a circle, the measure of an inscribed angle is half the measure of the central angle with the same intercepted arc.
- Learning objectives
- To show the difference between central angle and inscribed angle.
- To show that the measure of angle AOB is twice the measure of angle ACB if they intercept the same arc.
