In geometry, definitions are formed using known words or terms to describe a new word. There are three words in geometry that are not formally defined. These three undefined terms are point, line and plane.POINT (an undefined term)In geometry, a point has no dimension (actual size). Even though we represent a point with a dot, the point has no length, width, or thickness. A point is usually named with a capital letter. In the coordinate plane, a point is named by an ordered pair, (x,y).LINE (an undefined term)In geometry, a line has no thickness but its length extends in one dimension and goes on forever in both directions. A line is depicted to be a straight line with two arrowheads indicating that the line extends without end in two directions. A line is named by a single lowercase written letter or by two points on the line with an arrow drawn above them.PLANE (an undefined term)In geometry, a plane has no thickness but extends indefinitely in all directions. Planes are usually represented by a shape that looks like a tabletop or wall. Even though the diagram of a plane has edges, you must remember that the plane has no boundaries. A plane is named by a single letter (plane m) or by three non-collinear points (plane ABC).Undefined terms can be combined to define other terms. Noncollinear points, for example, are points that do not lie on the same line. A line segment is the portion of a line that includes two particular points and all points that lie between them, while a ray is the portion of a line that includes a particular point, called the end point, and all points extending infinitely to one side of the end point.Defined terms can be combined with each other and with undefined terms to define still more terms. An angle, for example, is a combination of two different rays or line segments that share a single end point. Similarly, a triangle is composed of three noncollinear points and the line segments that lie between them.Everything else builds on these and adds more information to this base. Those added things include all the theorems and other "defined" terms like parallelogram or acute angle.
The point, the line and the plane are the 3 undefined terms.The point, has no dimension. We represent a point with a do but it really has no size meaning it has has no length, width, or thickness. A point is usually designated with a capital letter. In the coordinate plane, a point is named by an ordered pair, (x,y).A line has no thickness but its length extends in one dimension and goes on forever in both directions. It is made up of an infinite number of points. We usually use a single lower case letter to denote a line, or we pick two points on the line and often draw a line segment above them.Last, a plane has no thickness but extends indefinitely in all directions. You might think of it as an infinite number of lines.The reason I mention that a plane can be thought of as infinite lines and a line as infinite number of points is to see how one undefined term leads to the next and then that one to the last.

You can give them any name that you like. Conventionally, points are named by capital Roman letters but you do not have to stick by that. You could, if you wanted to, name them after your best friends!

Is a point is named by a lowercase letter? I don't think so. A point is labeled by capital letters.

I got with a guy named nick.
Typically, a line is named with two points on the line.
you know about "capital" letters, right? well, capital means "the highest" and a state capital is the biggest, most important part of the state.
