Any way you like.
A point is generally denoted by an upper case Roman letter.
A line is denoted by a lower case Roman letter or by the two letters representing its end points.
A plane is usually "named" using its equation.
However, these are only conventions. As long as you describe what you have done, you can name them any way you like.
point, line and plane
A ray
When the line is inclined to the plane. That is, it is not in the plane nor is it parallel to it.
Point ; Line ; Plane - Remember the Point-Line-Plane Postulate
The line and the point define a plane.
Plane. A point has no dimension, a line has one dimension, and a plane has two dimensions.
point, line and plane
point * * * * * or, nothing (if the line is parallel to the plane).
A ray
plane
A plane intersects a line at a point, and i plane intersects another plane at a line.
When the line is inclined to the plane. That is, it is not in the plane nor is it parallel to it.
Unless the line is a subset of the plane, the intersection is a point.
Point ; Line ; Plane - Remember the Point-Line-Plane Postulate
The line and the point define a plane.
Point
A point - unless the line lies within the plane, or is parallel to it.
