9. an arc of a circle having measure less than or equal to 180 degrees
10. a line that intersects two points on the curve
12. is an arc of a circle having measure greater than or equal to 180 degrees
13. a half of a circle
15. is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle.
17. the point wear the tangent touches the circle
19. is the arc that is formed when segments intersect portions of a circle and create arcs
21. the distance around a circle
22. The center of a circle is the point which is equidistant from all points on the circle.

2. a line that is tangent to each of two coplanar circles
4. the length of an arc
5. circles with a common center
