Across
  1. 2. Points that do not lie on the same line
  2. 3. Represents location—drawn as a dot.
  3. 7. A point that divides a segment into 2 equal parts
  4. 10. Angle that measures less than 90 degrees but greater than 0 degrees
  5. 12. Lines that intersect to form right angles
  6. 14. Lines that cross at exactly one point.
  7. 16. Angle that measures exactly 90 degrees
  8. 17. This is formed by two rays or lines segments that share one endpoint
  9. 20. Points that do not lie on the same plane
  10. 21. A two dimensional flat surface
  11. 22. Angle that measures exactly 180 degrees
Down
  1. 1. This symbol means same size and shape
  2. 4. Angle that measures less than 180 degrees but greater than 90 degrees
  3. 5. A straight path extending infinitely in both directions, shown with arrows at each end.
  4. 6. Points that lie in the same plane
  5. 8. Two lines that never intersect and stay the same distance apart
  6. 9. Points that lie on the same line
  7. 11. Part of a line that has two endpoints
  8. 13. Common endpoint where two rays or segments meet
  9. 15. Two lines that do not intersect and are not parallel.
  10. 18. Rays 2 rays with a common endpoint that point in opposite directions and form a straight line.
  11. 19. This starts at a given point and extends infinitely in one direction, drawn with one arrow.
