Circle Geometry Rerms

2. The circumference divided by the diameter.
5. A central angle is _________ the inscribed angle.
8. An angle formed by two radii.
9. A point that is equidistant from all points on the edge of a circle.
10. Circles that share the same center.
13. Angles that add to 180 degrees.
15. Half a circle (180 degree arc).
17. Vertex formed on the edge of the circle while the sides are chords.
18. The angle between a tangent line and line connecting the point of tangency and center of the circle.
19. Angles that add to 90 degrees.

1. A arc subtended by a central angle that is less than 180 degrees.
3. Pie-slice shape of a circle formed by two radii.
4. A straight line that passes through the center (longest chord).
6. A line that connects the center to the edge of a circle.
7. An arc that is more than half the diameter.
11. Circles that are the same radius/size.
12. A line that touches a circle at exactly one point.
14. Part of the diameter of a circle.
15. Opposite to
16. A straight line that connects two points on the circle (not necessarily through center).
