What are the three undefined terms in geometry and their definitions?

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.

What are the three building blocks of geometry?
There are Four building blocks of geometery. They are; theorems, postulates, definitions, and undefined terms. They are terms that prove statements in geometery. The undefined terms include a point, line and plane.
What three things are accepted as true without verification or proof?
Definitions, postulates, and undefined terms
Describe each term of 3 undefined terms in geometry?
There are typically three words in geometry that are undefined. The first is "point." A point has no dimension, length, width, or thickness. The second is "line." A line has no thickness and goes on indefinitely in both directions. The third undefined term is "plane." A plane has no thickness and has no boundaries.
Why it is called undefined terms in geometry?
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.

Is it possible to define all th terms in geometry including the three terms?
the three terms; point, line and plane can be defined although it is called the undefined terms still we know and we can define the meanings of that terms.. common sense? joke.
