Across
  1. 3. angles that are on the same side of the transversal and are outside the other two lines
  2. 5. a perpendicular line or segment that passes through the midpoint of segment
  3. 7. are created by two distinct rays that share a common endpoint
  4. 9. two nonadjacent angles formed by intersection lines or segments
  5. 11. the property of a polygon whose sides are all congruent
  6. 12. two angles whose sum is 180 degrees
  7. 13. a transformation that "slides" each point of a figure the same distance in the same direction
  8. 16. angles formed when a transversal crosses two parallel lines. These angles are on opposite sides of the transversal and are in between the other two lines.
  9. 17. angles formed when a transversal crosses two parallel lines. These angles are on opposite sides of the transversal and are outside the other two lines.
  10. 18. sides that have the same relative position in geometric figures
Down
  1. 1. divides a segment or angle into two equal parts
  2. 2. angles that are on the same side of the transversal and are between the parallel lines
  3. 4. the property of a polygon whose angles are all congruent
  4. 6. angles that have the same relative position in geometric figures
  5. 8. a transformation that "flips" a figure over a line of reflection
  6. 10. having the same size, shape, and measure.
  7. 14. a transformation that turns a figure about a fixed point through a given angle and a given direction
  8. 15. angles in the same plane that have a common vertex and common side, but not common interior points.
