A line is a one-dimensional geometric figure having length but no width. It is made up of points that are extended in opposite directions infinitely. The different types of lines are horizontal, vertical, parallel, perpendicular, curved, and slanting lines. The definitions of each type of line with an image are given below. Go through the entire article to learn in detail about the Types of Lines in Geometry and examples for each one of them.

## What is a Line?

A line can be defined as the set of points that is extended in opposite directions. It has no width, no endpoints in opposite directions and it is a one-dimensional plane. The line has no thickness.

### Types of Lines

There are different types of lines in geometry, the basic types of lines are listed below. Let us discuss in detail the figures, definitions, properties of each one of them. They are along the lines

- Vertical Lines
- Horizontal Lines
- Parallel Lines
- Skew Lines
- Perpendicular Lines
- Oblique or slanting lines
- Concurrent Lines
- Transversal line
- Coplanar Lines

**Straight Lines:**

Straight lines are the lines as shown below.

**Horizontal Lines:**

If the line moves from the left to the right side in a straight direction, it is called the horizontal line.

**Vertical Lines:**

If a line moves from the top to the bottom in a straight direction, then it is a vertical line.

**Parallel Lines:**

When two straight lines don’t intersect at any point, then they are parallel lines.

**Perpendicular Lines:**

When two straight lines meet at an angle of 90 degrees, then they are perpendicular lines.

**Oblique or slanting lines:**

If the lines are drawn in a slanting position, then they are called the oblique or slanting lines.

**Skew Lines:**

If two non-parallel lines are not intersecting in a space, then they are called the skew lines.

**Concurrent Lines:**

When two or more lines are passing through a common point, then those lines are called concurrent lines.

**Transversal line:**

A transversal line is a straight line that cuts 2 or more lines. The lines may or may not be parallel.

**Coplanar lines:**

Coplanar lines are lines that lie on the same plane.

### Frequently Asked Questions on Types of Lines

**1. What are the different types of lines?**

The various types of lines are Horizontal Line, Vertical Line, Parallel Lines, Perpendicular Lines, Skew Lines, Oblique or slanting lines, Coplanar Lines, Concurrent Lines, and Transversal line.

**2. Define a Line?**

A straight line is a one-dimensional figure that has no thickness and extending infinitely from the extreme directions.

**3. What is a line segment?**

A line segment is a part of the line that has two fixed endpoints and it can’t be extended infinitely.

**4. What are parallel and perpendicular lines?**

When two straight lines extend in both directions and they don’t meet at any point is called parallel lines. Perpendicular lines intersect each other at right angles.
