  1. 3. Points that don't lie on the same plane
  2. 4. A line Segment with an associated direction
  3. 6. A location with no size or shape
  4. 8. Made up of points with no thickness or width
  5. 9. A segment, line, or plane that intersects a segment at its midpoint
  6. 10. The formula used to find the distance between two points on a coordinate plane
  7. 11. The "rise" of a directed line segment
  8. 13. A line segment or ray Perpendicular to a segment at its midpoint
