# What is the Opposite(Antonym) of “coplanar”?

## The Opposite(Antonym) of “coplanar”

The antonyms of coplanar are noncoplanar and nonplanar. These words describe geometric figures that either lie on the same plane or not.

## Definitions and Examples of noncoplanar, nonplanar

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

### noncoplanar

Not lying on the same plane.

Example

The four points were noncoplanar, so they could not form a square.

### nonplanar

Not lying on a flat surface or plane.

Example

The curved surface of the sphere is nonplanar.

## Key Differences: noncoplanar vs nonplanar

• 1Noncoplanar refers to points or lines that do not lie on the same plane, while nonplanar refers to surfaces that are not flat.
• 2While coplanar objects can be visualized in two dimensions, noncoplanar and nonplanar objects require three dimensions to be represented.

## Effective Usage of noncoplanar, nonplanar

• 1Geometry: Use these antonyms to describe the position of points, lines, and surfaces in space.
• 2Mathematics: Incorporate these antonyms when solving problems related to geometry and trigonometry.
• 3Science: Utilize these antonyms when discussing molecular structures and chemical bonding.
📌

Remember this!

The antonyms noncoplanar and nonplanar describe geometric figures that do not lie on the same plane or flat surface. Use these words in geometry, mathematics, and science to describe the position of points, lines, and surfaces in space, solve problems, and discuss molecular structures and chemical bonding.
