6. An arc less than 180 degrees.
8. with the same diameter.
9. A line that intersects with a circle at two points.
14. A polygon whose segments are tangent to a circle.
16. A chord that intersects with the center of a circle.
17. The ratio of a circle's circumference to its diameter.
19. The point from which all points on a circle are equidistant.
20. A geometric figure composed of points that are equidistant from a given point.
21. A 180 degree arc.
22. A polygon whose vertices intersect with a circle.
24. A line that intersects with a circle at only one point (the point of tangency).
25. An angle whose vertex is the center of a circle.

1. A segment with one endpoint at the point of tangency of a circle and the other endpoint on the tangent line.
2. An arc greater than 180 degrees.
3. An arc that is formed when two segments, lines, or rays intersect a circle.
4. Circles that share a center.
7. The region within a circle bounded by a chord of that circle and the minor arc whose endpoints are the same as those of the chord.
10. The point of intersection between a circle and its tangent line or tangent segment.
11. Two endpoints on a circle and all of the points on the circle between those two endpoints.
12. The same distance. Objects can be equidistant from one another.
13. A region inside a circle bounded by a central angle and the minor arc whose endpoints intersect with the rays that compose the central angle.
15. a collection of points in space that is equidistant from a fixed point given a fixed distance.
18. A segment with one endpoint at the center of a circle and the other endpoint on the circle.
23. A segment whose endpoints are on a circle.
