Point has no dimensions. It is represented by dot.

Line has one dimension. It is represented by a line with two arrowheads but it extends without end.

Plane has two dimensions. It is represented by a shape that looks like a floor or a wall, but it extends without end.

Space has three dimensions.

Intersections:

Two or more geometric figures intersect if they have one or more points in common.

The intersection of the figures is the set of points the figure have in common.

The intersection of two different lines is a point.
