  1. Circle
    set of coplainer points equidistant from a given point
  2. center
    the given point
  3. radius
    a segment starting at the center and ending on the circle
  4. Rule-
    all radii in a circle are equal or congruent
  5. chord
    a segment starting and ending on the circle at different points
  6. diameter
    a chord that contains or goes through the center
  7. secant
    a coplainer line that contains a chord
  8. Tangent
    a coplainer line that intersects a cicle at only one point
  9. Point of Tangency
    the point where the tangent and the circle meet
  10. Congruent Circles
    two or more circles that have congruent or equal radii
  11. Concentric circles
    two or more coplainer circles with the same center
  12. sphere
    the set of points equidistant from a given point (3-D)
  13. Common Tangent
    a coplainer line that is tangent to two coplainer circles
  14. Internal Common Tangent
    a common tangent the intersects the segment joining the two centers
  15. External Common Tangent
    a common tangent that does not intersect the segment joining the two centers
  16. Tangent circles
    two coplainier circles that intersect at only one point
  17. internally tangent circles
    two coplainier circles that are tangent with one inside the other
  18. externally tangent circles
    two coplainier tangent circles that are not inside of each other
  19. arc
    a set of points that are part of a circle starting and ending at different points
  20. minor arc
    an arc that is less than half the circle (two letters)
  21. major arc
    an arc that is more than half the circle (three letters)
  22. Semi-Circle
    an arc that is equal to one half the circle (three letters if possiable)
  23. Arc addition postulate
    if two arcs have a common end point only then the measure of the first arc plus the measure of the second arc equal the measure of the new arc form
  24. congruent arcs
    two arcs on the same circle (or congrunet circles) that have the same or equal measures
  25. midpoint of an arc
    the point on an arc that divides the arc into two equal or congruent parts
  26. Inscribed polygon
    a polygon drawn inside a circle with all vertics on the circle
  27. Circumscribed circle
    a circle drwn around a polygon touching all vertices
  28. Inscribed circle
    a circle drawn inside a polygon touching all sides
  29. Circumscribed polygon
    a polygon drawn around a circle with all sides touching the circle
