Aug 13, 2024 · This chapter discusses the definitions and examples of point, line, ray, line segment and a plane. How two or more than two lines can make when meet at some point for example intersecting lines, perpendicular lines, parallel lines, transversal lines and concurrent lines with the help of diagrams.
Aug 12, 2022 · When you see lines or structures that seem to run in the same direction, never cross one another, and are always the same distance apart, there’s a good chance that they are parallel. Perpendicular lines are two lines that intersect at a 90º (right) angle.

- A Line Segment and A Ray
A point is a dot in a plane or a piece of paper. A point does not have any length, width or height. It determines the location or position in a plane. Put a dot on a paper and mark it as A or with any capital letter, to show a point. Now if you want to show three different points, then put three dots on a paper and mark them as X, Y and Z. We can r...
A line is a straight path formed by connecting a set of points in a plane. It is a one-dimensional shape that has length but no width and height. A line extends infinitely in both ends towards opposite directions. We can use upper case letters to denote a line. Also, a line can be marked with a single small letter, such as m, l, etc. For example, A...
A line segment is a line that has two definite endpoints. If a line segment has two endpoints A and B, then it is denoted by AB bar. A ray is a line that starts from a point and extends indefinitely in a direction. It has only one endpoint. An example of a ray is a torch light that starts from an end and goes endlessly in one direction.
We know when two lines meet we get a point. When two points on a plane surface are joined, a straight line segment is obtained. But if two points in a curved surface is joined, a curved line segment is drawn. When a line segment is extended towards both sides unlimitedly it becomes a line.

- Line Segment. A line segment is a part of a line with two end-points. It is the shortest distance between two points and has a fixed length.
- Ray. A ray is a part of a line, which has a starting point and extends infinitely in one direction.
- Perpendicular Lines. When two lines form a right angle with each other, by meeting at a single point, are called perpendicular lines. In the figure, you can see, lines AB and CD are perpendicular to each other.
- Parallel Lines. Two lines are said to be parallel when they do not meet at any point in a plane or which do not intersects each other. In the figure, lines PQ and RS are parallel to each other.
1 day ago · Figure 10.3 Basic Geometric Symbols for Points and Lines. From Figure 10.3, we see the variations in lines, such as line segments, rays, or half-lines. What is consistent is that two collinear points (points that lie on the same line) are required to form a line.

A line is a straight path of points that continues in two directions. A line segment has definite length; every line segment has two endpoints. A horizontal line runs left to right. A vertical line runs up and down. Parallel lines run in the same direction. Two lines meet (or cross) at a point of intersection.
