notes

Points:

  • By a sharp tip of the pencil, mark a dot on the paper. Sharper the tip, thinner will be the dot. This almost invisible tiny dot will give you an idea of a point.

  • A point is a zero-dimensional object as it has no length, width, or height. It has no size. It tells about the location only. A point is dimensionless.

  • These are some models for a point: If you mark three points on a paper, you would be required to distinguish them. For this they are denoted by a single capital letter like A, B, C. It is usually denoted by a capital letter.

  • These points will be read as point A, point B, and point C.
