Answers
Answer:
line segment has two endpoints. It contains these endpoints and all the points of the line between them. You can measure the length of a segment, but not of a line. ... A ray is a part of a line that has one endpoint and goes on infinitely in only one direction. You cannot measure the length of a ray.Two lines that meet in a point are called intersecting lines. A part of a line that has defined endpoints is called a line segment.
and rays. Identify and draw lines, line segments, and rays in practice problems. ... Practice: Identify points, lines, line segments, rays, and angles · Lines ...

Answer:
Point
Point is the basic building block of Geometry. Every shape is made through the combining the points.
A small dot marked by a pencil is a point. A point has no length or width. It has no thickness. Point is a mark of position. A point specifies the exact location. Point is denoted by a dot (.) and is named by an alphabet.

In the figure above, O is a point as it has a definite mark. Here it indicates this point O is located at the centre of the plane. In the figure below, there is another point A. It is located at right bottom of the plan.

Ray
Let us think of a torch. The light rays come out of it and move away. Let us take example of sun. The rays start from sun and go in all directions and reach to us.
In Geometry also, a ray starts from a point and may go to infinity. It has staring point but has no end point. We say a ray has one endpoint and goes without end in one direction.

In the figure above, the starts from A and the arrow denotes it can go to infinity.
Its length cannot be measured. An unlimited number of rays can be drawn in different directions from a given point
The rays coming from torch or sun are examples of rays.
This is a ray because a ray has one endpoint and goes without end in one direction
Line

Look at the figure above. There are arrows on both sides. It indicates it can go further on both sides without end. This is called line.
A line goes without end in both directions. Both ends of a line can go to infinity. A line has no end points. The length of a line cannot be measured. A line has no definite length.
A line is named by any two points on it and written as line AB or line PQ. One and only one line can be drawn passing through two given points A and B. This line is called AB. It may also be called BA. Line BA is the same as line AB. Both pass through the same two points A and B.
An unlimited number of lines can be drawn passing through a given point A.
A horizontal line goes straight left or right across. A vertical line goes straight up or down.
A diagonal line can be in any direction between horizontal line and vertical line.
Line Segment

Now look at the figure above. There is no arrow on any end. It starts from one point and ends at another point. This is called a line segment. A section of a line is a line segment.
A line segment has two endpoints. A line segment is a straight line that connects two points. It is the shortest path between the two points. A line segment has definite length. Its length can be measured.
Let us mark two small dots (.) by a pencil as points A and B. Let us join them by drawing a straight line. This forms a line segment. A line segment is named by its two endpoints and written as line-segment AB or line-segment PQ.

In the figure above, a line segment AB has two end points A and B. It starts from point A and ends at point B. One and only one line-segment can be between two given points A and B. This line-segment is called AB. It may also be called BA. Line BA is the same as line AB. Both pass through the same two points A and B.
Line segment can also be a part of a line as in the figure below.

A line-segment may be also a part of ray. In the figure below, a line segment AB has two end points A and B. It is a part of a ray starting from A.

Parallel lines
Two lines in the same plane either meet or do not meet. If the two lines on a plane meet, we say the two lines intersect and the point where they meet is called point of intersection. If the two lines cannot meet at any point, they are called parallel lines. No two points can be common to two parallel lines.

In the figure above, the two lines do not intersect each other. Even if we extend these lines further, they will not touch or meet each other. They are parallel lines.
Intersecting lines

Let us look at the two lines AB and CD in figure above. They intersect at point O. Hence they are not parallel lines. Point O is the point of their intersection.
Concurrent lines
Three or more lines passing through the same point on a plane are called concurrent lines. In the figure below, the three lines AB, CD and EF intersect each other at point O.

Collinear points
Three or more points in a plane* are said to be collinear if they all lie on the same line.

In the figure above, points A, B and C are on the same line. Hence these three points A, B and C is collinear.
*Flat surface is called a plane in Geometry. We can say a piece of paper from our Exercise Book is a plane.
