Jul 25, 2023 · Definition. In geometry, when points lie on the same line, they are said to be collinear. Collinearity is a property that relates points and lines in a geometric space. If two or more points fall on the same straight line, they are known as collinear points. For instance, in a two-dimensional plane, if you draw a straight line, any number of ...

In geometry, a line is a straight one-dimensional figure that does not have a thickness, and it extends endlessly in both directions. Diagram A represents a line. It does not have any endpoint. The two arrows at each end signify that the line extends endlessly and is unending in both directions. The length of a line cannot be measured. Diagram A: L...
A line segment, which is part of a line, has two defined endpoints. Diagram B represents a line segment with two endpoints, A and B. A line segment can be measured, whereas a line cannot. The length of the line segment is the distance between the two endpoints, A and B. Diagram B: Line Segment 1. Let’s draw a line To draw a line, take a pencil, a r...
Now Let’s understand the different types of lines. 1. Straight Line A line is a set of collinear points with no curvesand extends limitlessly in opposite directions is called a Straight line. 1. Curved Line A line is a set of collinear points which has a curvature or bend in its formation is called a Curved Line. 1. Oblique Line An oblique is a lin...
Option B is made up of 3 line segments and a curved part. Option C is a circle hance it is made up of only curved parts. Option D is made up of 4 line segments. ∴ ∴ Options A and D are correct. Example 2. Find the correct types of lines from the figure given below. Solution. Option A is a pair of parallel lines.
Between two points, the line is straight if it is the shortest path between them. If it is not the shortest path then it is not a straight line. Wait! What about the second line we’ve drawn? This is a special case because it is not one, but multiple lines. The line that joins A with C. The line that joins C with D. The line that joins D with E.
Lines. A line is a one-dimensional figure, which has length but no width. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane. The two points which lie on the same line are said to be collinear points.

- A line is a figure in geometry, which has only length and no width in a two-dimensional plane and extends infinitely in opposite directions.
- In geometry there are four types of lines: Horizontal Line Vertical lines Parallel lines Perpendicular lines
- A vertical line is a line drawn from the bottom to the top in a straight direction.
- A horizontal line is a line drawn from left to right in a straight direction.
- A line segment is a part of line which has two fixed endpoints.
For example, Each side of a rectangle is made of a line segment that is part of a line. The opposite sides of a rectangle are parallel. There are also many examples of parallel lines in real life. For example, The lines that pass by the legs of a table are parallel. Step-by-step guide: Parallel lines.
