Whether you wish to learn the names of geometric lines for professional reasons or simply to better be able to refer to things in your day-to-day speech, this section is the best place to start. If you are trying to describe something, for example, a diagonal line, this knowledge is very useful to have.

This is a great way to create a wider English vocabulary and will also benefit you in both spoken and written English. Understanding these words will also help with your reading since lines are often used as descriptive terms in writing.

### Line Names with Examples and Pictures

**Straight **

A straight line is a line that extends infinitely in both directions and does not curve or bend.

Example: The ruler drew a straight line from one end of the paper to the other.

**Diagonal **

A diagonal line is a line that slants or slopes at an angle, connecting two nonadjacent corners or points on a surface.

Example: The road cuts diagonally across the field, making a shorter path to the other side.

**Vertical **

A vertical line is a straight line that runs from top to bottom or bottom to top, perpendicular to the horizontal plane.

Example: The flagpole stood tall and straight, with a vertical line running from the ground to the top of the flag.

**Parallel lines **

Parallel lines are two or more lines that never intersect or meet, no matter how far they are extended in either direction.

Example: The train tracks run parallel to each other, creating a straight path for the train to travel on.

**Curved **

A curved line is a line that changes direction gradually, creating a smooth and flowing shape.

Example: The roller coaster track was full of curved lines and loops, making for an exciting ride.

**Horizontal **

A horizontal line is a straight line that runs from left to right or right to left, perpendicular to the vertical plane.

Example: The horizon appeared as a straight, horizontal line where the sky met the sea.

**Dotted**

A dotted line is a line made up of a series of dots, with small gaps in between each dot.

Example: The dotted line on the map showed the route of the hiking trail through the forest.

**Wavy **

A wavy line is a line that moves in a zigzag pattern, with a series of curves and bends.

Example: The river flowed in a wavy line through the valley, creating a beautiful and natural landscape.

**Zigzag **

A zigzag line is a line that moves back and forth in a sharp, angled pattern, resembling the letter “Z”.

Example: The lightning bolt left a zigzag line in the sky as it flashed through the storm clouds.

## Frequently Asked Questions

**What are the 7 types of lines in geometry?**

There are seven types of lines in geometry, which include straight, curved, vertical, horizontal, diagonal, perpendicular, and parallel lines. Each type of line has its unique characteristics and properties that define them.

**What are the names of the lines in geometry?**

In geometry, there are various names of lines such as line segment, ray, and open and closed curves. A line segment is a part of a line that has two endpoints, while a ray has one endpoint and extends infinitely in one direction. Open curves are lines that do not form a closed shape, while closed curves are lines that form a closed shape.

**What are 10 basic geometric terms?**

The ten basic geometric terms include point, line, plane, angle, perpendicular, parallel, circle, sphere, triangle, and rectangle. Points are the most fundamental geometric figures, while lines are made up of points. Planes are two-dimensional surfaces that extend infinitely in all directions.

**What is a line in geometry?**

In geometry, a line is a one-dimensional figure that extends infinitely in both directions and has no thickness. A line is defined by an infinite number of points and can be straight or curved.

**What are some geometry words that start with ‘b’?**

Some geometry words that start with ‘b’ include bisect, base, and binary. Bisect refers to dividing an angle or a line into two equal parts. The base is the bottom part of a two-dimensional figure, while binary refers to a system of numerical notation that uses only two digits (0 and 1).

**What are some geometry words that start with ‘j’?**

There are not many geometry words that start with ‘j,’ but one such word is a joint. A joint is a point where two or more lines or planes meet. It is also known as an intersection point.
