Define Points, Lines, and Spaces

Points, lines, and planes are known as undefined or primitive terms. These are the most significant and fundamental concepts in the study of geometry. They are so basic that we will explain them in place of of define them.

v PointsA point has no length, width or height; it points out a position. generally we use a capital letter to name a point and utilize a dot to represent it in figures. We call the points below point A, point B and point C.
