3. interior of a circle The set of all points inside the circle.
exterior of a circle The set of all points outside the circle.

5. Identify each line or segment that intersects L.

10. Example 5
Assume that lines that appear to be tangent are tangent. C is the center of each circle. Find the value of x.
65° + 90° +.5x° = 180°
.5x° = 25°
x = 50°

12. Example 6 HK and HG are tangent to F. Find HG. 4+2a = 5a – 32 a = 12
