  1. 1. Is the set of all points in a plane that are equidistant from a given point called the center of the circle.
  2. 2. an arc whose measure is less than 180 degrees
  3. 5. is a line in the plan of a circle that intersects the circle at exactly one point also called the point of tangency
  4. 6. is an angle of a circle whose vertex is the center of the circle
  5. 7. is a line that intersects a circle in two points
  6. 8. a line or segment that is tangent to two coplanar circles
  7. 11. is a segment whose endpoints are on the circle
  8. 12. is an arc with endpoints that are endpoints of a diameter (180 degrees)
  9. 13. if and only if the circles have the same measure and they are arcs of the same circle or of congruent circles.
