Across
  1. 2. The circumference divided by the diameter.
  2. 5. A central angle is _________ the inscribed angle.
  3. 8. An angle formed by two radii.
  4. 9. A point that is equidistant from all points on the edge of a circle.
  5. 10. Circles that share the same center.
  6. 13. Angles that add to 180 degrees.
  7. 15. Half a circle (180 degree arc).
  8. 17. Vertex formed on the edge of the circle while the sides are chords.
  9. 18. The angle between a tangent line and line connecting the point of tangency and center of the circle.
  10. 19. Angles that add to 90 degrees.
Down
  1. 1. A arc subtended by a central angle that is less than 180 degrees.
  2. 3. Pie-slice shape of a circle formed by two radii.
  3. 4. A straight line that passes through the center (longest chord).
  4. 6. A line that connects the center to the edge of a circle.
  5. 7. An arc that is more than half the diameter.
  6. 11. Circles that are the same radius/size.
  7. 12. A line that touches a circle at exactly one point.
  8. 14. Part of the diameter of a circle.
  9. 15. Opposite to
  10. 16. A straight line that connects two points on the circle (not necessarily through center).
