  1. 3. - a segment whose endpoints lie on a circle. straight line through the circle.
  2. 7. arc - an arc of a circle whose measure is less than 180 degrees. an arc of a circle having measure less than or equal to radians.
  3. 9. - a dilation with a scale factor greater than 1. also known as expansion.
  4. 10. rays - two rays that have a common endpoint and form a line. both start from a common point and go off in exactly opposite directions.
  5. 12. circles - when two circles have a congruent radii. when the two circles are the same size.
  6. 15. circles - are coplanar circles with the same center. circles with a common center.
  7. 16. - the ratio of the length of the leg opposite the angle to the length of the hypotenuse. equal to the ratio of the side opposite a given angle to the hypotenuse.

  1. 1. tangent - a line tangent to two circles. intersects the segment that joins the center of the two circles.
  2. 2. - part of a circle connecting two points on the circle. a portion of the circumference of a circle.
  3. 4. of a circle - the set of all points inside the circle. the set of points whose distance from the center is less than the radius.
  4. 5. arc - consists of endpoints that lie on the sides of an inscribed angle and all the points of the circle between them. created when segments intersect a part of the circle.
  5. 6. - an angle if its endpoints lie on the sides of the angle. form at a particular point when straight lines from its extremities are joined at a point.
  6. 8. angle - an angle whose vertex on a circle and whose sides contain chords of the circle.
  7. 11. of tangency - the point where the tangent and a circle intersect. the point where the alignment changes from a circular curve to a straight line or tangent.
  8. 13. circles - two coplanar circles that intersect at exactly one point. circles in a common plane that intersect in a single point.
  9. 14. of a circle - a region bounded by an arc of the circle and the two radii to the arc’s endpoints.
  10. 19. - the ratio of the length of the leg adjacent to the angle to the length of the hypotenuse. equal to the ratio of the side adjacent to an acute angle to the hypotenuse.
