## Definitions and Examples of linear, straight, planar

Learn when and how to use these words with these examples!

Arranged in or extending along a straight or nearly straight line.

Example

The graph of a **linear** function is a straight line.

Extending uniformly in one direction without curves or bends.

Example

A **straight** line is the shortest distance between two points.

Having a flat or level surface.

Example

A cube has six **planar** faces.

## Key Differences: linear vs straight vs planar

- 1
**Linear**describes a shape that extends along a straight or nearly straight line. - 2
**Straight**describes a shape that extends uniformly in one direction without curves or bends. - 3
**Planar**describes a shape that has a flat or level surface.

## Effective Usage of linear, straight, planar

- 1Mathematics: Use these antonyms to describe different types of functions, graphs, and geometric shapes.
- 2Physics: Incorporate these antonyms to describe the motion of objects and the path of light rays.
- 3Design: Utilize these antonyms to describe different types of curves and lines in art and architecture.

Remember this!

The antonyms of **parabolic** describe shapes that are different from the curved, U-shaped form of a parabola. **Linear** extends along a straight or nearly straight line, **straight** extends uniformly in one direction without curves or bends, and **planar** has a flat or level surface. These antonyms can be used in mathematics, physics, and design to describe different types of functions, graphs, geometric shapes, motion of objects, path of light rays, and curves and lines in art and architecture.
