Circles

1. / pie shaped portion of the area of the circle
3. / basically a pie chart
4. / a line that intersects two points on the curve
5. / the angle at the center by two given points on the circle
6. / tooth geometry
7. / the distance around the circle
8. / a chord that passes through the center of the circle
9. / polygon whose segments are tangent to a circle
14. / center of the circle
15. / the ratio of a circles circumference to it's diameter
16. / a polygon who's vertices interact with a circle
17. / part in circle bounded by chord of that the circle and minor arc whos end points are same chord
18. / part of circle that is defined by two end points
19. / line segment that joins two points on the circumference of a circle
20. / the point radius from the points on the edge
22. / flat shape like a ring

1. / branch of geometry that deals with great circles and spheres
2. / line that intersects the circle in exactly one point
9. / circles that have the same center but different radius
10. / circles that have the same radius
11. / has a measure that greater than 180 degrees
12. / half circle
13. / has a measure that is less than 180 degrees
16. / the angle sub tended at a point on the circle by two given points in a circle
21. / a segment with end points in the center of the circle
