The point where these lines meet is called the intersection point. Intersecting lines are two or more lines that meet or cross or intersect at a common point. Other than diagonal lines, these are called oblique lines as well. Diagonal Linesĭiagonal lines are lines which are neither go in a horizontal direction nor in a vertical direction as these lines are at that slant whose slope lies between horizontal and vertical. These lines go in the up and down direction and we can see these lines in the real world as poles, multi-floor buildings, columns to support structures, etc. In other words, those lines which are perpendicular to the ground level are called vertical lines. Vertical lines are opposite to the horizontal lines and are parallel to the verticle axis i.e., the y-axis. We can see the horizontal lines in the real world in infrastructure or buildings. In algebra, we can represent the horizontal lines using the equation y = constant. In other words, those lines which go from left to right or vice versa are called horizontal lines. Horizontal lines are those lines, that are parallel to the horizontal axis i.e., the x-axis or the ground level. We can extend straight lines indefinitely in both directions and still, the line has the same constant slope i.e., the angle from the positive x-axis. These lines are characterized by having the same direction and no curvature at all. Straight Lines are those lines that do not deviate from a linear path even after extending to infinity length. Let’s discuss these types in detail as follows: Types of Lines Based on Shapeīased on the shape or change in direction, we can classify the lines as: There are various different types of lines in geometry, having various different properties and characteristics. Represented by a line segment with two endpointsĬan intersect with other geometric figures at the endpoint or along its pathĬan intersect with other geometric figures at the endpoints or along its pathĬan intersect with other geometric figures at any point on the line. Represented by a starting point and an arrow indicating the direction Named by a single alphabet generally lowercase. Named by the endpoint and any other point on the ray It is generally represented by a straight line with arrowheads on both ends where the arrowhead represents the indefinite extension.Ī portion of a line with one endpoint that extends infinitely in one direction As lines can be extended indefinitely, it has no endpoints and it also has infinity length as well. In Euclidean geometry, we define the line as, a one-dimensional shape i.e., a length without any breadth. Line is the combination of infinite points that extend to infinity in both directions. So let’s start out learning about the lines and their different types. We will also learn about some special lines such as tangents, secants, and lines of symmetry. In this article, we will deal with different types of lines, such as straight, curved, horizontal, vertical, parallel, intersecting, bisecting, and transversal as well. We can see a lot of different types of lines around us in the real world, from railway tracks to crossroads on the highway, we can see the use of lines around us. A line can be defined as “a breadthless length”, which is the definition according to Euclid. Line is a one-dimensional geometric shape, which lays the foundation of two and three-dimensional geometry. Role of Mahatma Gandhi in Freedom Struggle.
