5 objects that could represent a point, a line, a plane are:

  1. A dot of a chalk on a blackboard: A dot is a point so it is an object that could represent a point.
  2. Railway tracks: They represent parallel lines and they are never ending. Lines do not end.
  3. Blackboard: A blackboard can be represented by a plane.
  4. A sharpened pencil: We see that a pencil which is sharpened is an example of a line because it represents the figure of a line.
  5. Laptop: A laptop is a plane.

A point is simply a dot, and it can be formed as follows:
