Is a line segment defined or undefined?
Line segment: A line segment which extends indefinitely in both directions gives a line. Other term involved is line. We keep the line as undefined term. The only thing is that we can represent in intuitively or explain it with the help of physical model.
Is an line a defined term?
In geometry, we have three undefined terms, and those are a point, a line, and a plane. These are coined as undefined, because we cannot define them using other geometrical terms.

What makes something a defined term?
Defining a term gives that word or phrase a particular, special meaning within the context of the legal document, and not the meaning that would be used in everyday language. This happens mostly to general words when we want to narrow the range of its meaning.
Why is a ray a defined term?
What Is a Ray in Math? The definition of ray in math is that it is a part of a line that has a fixed starting point but no endpoint. It can extend infinitely in one direction. Since a ray has no end point, we can't measure its length.

A line segment is named by its endpoints, but other points along its length can be named, too. Each portion of the line segment can be labeled for length, so you can add them up to determine the total length of the line segment.
What are some examples of line segments?
Real-world examples of line segments are a pencil, a baseball bat, the cord to your cell phone charger, the edge of a table, etc. Think of a real-life quadrilateral, like a chessboard; it is made of four line segments. Unlike line segments, examples of line segments in real life are endless.
What is a line?

How to find line segments of diagonals?
Recall that the Pythagorean Theorem is a2 + b2 = c2 a 2 + b 2 = c 2 for any right triangle. A diagonal on a coordinate grid forms the hypotenuse of a right triangle, so can quickly count the units of the two sides:

A special case of the Pythagorean Theorem is the Distance Formula, used exclusively in coordinate geometry. You can plug in the two endpoint x- and y- values of a diagonal line and determine its length. The formula looks like this:
What is the coordinate plane?
A coordinate plane, also called a Cartesian plane (thank you, René Descartes!), is the grid built up from a x-axis and a y-axis. You can think of it as two perpendicular number lines, or as a map of the territory occupied by line segments.
