# Are points D and E collinear or coplanar?

**Points D**,

**E**, and F lie on the same line. So, they are

**collinear**.

**Points D**,

**E**, F, and G lie on the same plane, so they are

**coplanar**.

Also, are coplanar points also collinear?

**Collinear points** are all in the same line. **Coplanar points** are all in the same plane. So, if **points** are **collinear** then we can choose one of infinite number of planes which contains the line on which these **points** lie => so they **are coplanar** by definition.

Also Know, what is collinear and coplanar? **Collinear**: points are **collinear** if all of them are in the same straight line. **Coplanar**: points are **coplanar** if all of them are in the same PLANE. Two points are allways **collinear**. This is the simpliest way to draw a line. Three points in space are allways **coplanar**, but not necesarily **collinear**.

Also to know is, what is the difference between collinear points and coplanar points?

**Collinear points** are **points** all in one line and non **collinear points** are **points** that are not on one line. Below **points** A, F and B are **collinear** and **points** G and H are non **collinear**. **Coplanar points** are **points** all in one plane and non **coplanar points** are **points** that are not **in the** same plane.

What is an example of coplanar?

**Coplanar**. Points or lines are said to be **coplanar** if they lie in the same plane. **Example** 1: The points P , Q , and R lie in the same plane A . They are **coplanar** .
