Theorem 6.13
If a tangent and a chord intersect at a point on the circle, then the measure of each angle formed is one half the measure of its intercepted arc.

3. Example: Line m is tangent to the circle. Find the indicated measure.
1) angle ) arc EFD

4. Vocabulary Angles Inside the Circle
If two chords intersect inside a circle, then the measure of each angle is one half the sum of the measures of the arc intercepted by the angle and its vertical angle.

5. Example:
Find the value of x.

6. Vocabulary Angles Outside the Circle
If a tangent and a secant, two tangents, or two secants intersect outside a circle, then the measure of the angle formed is one half the difference of the measures of the intercepted arcs.

7. Example:
Find the value of x.
