# CoplanarQ (1.0.0)current version: 2.0.0 »

Determine whether a set of points lies in a plane

Contributed by: Wolfram|Alpha Math Team
 ResourceFunction["CoplanarQ"][{list1, list2, …}] returns True if the set of points determined by listi lies in a plane.

## Details and Options

ResourceFunction["CoplanarQ"] accepts numeric and symbolic arguments.

## Examples

### Basic Examples (3)

Any set of three points of the same dimension lie in a plane:

 In[1]:=
 Out[1]=
 In[2]:=
 Out[2]=

Add a fourth point that lies in the same plane:

 In[3]:=
 Out[3]=
 In[4]:=
 Out[4]=

A set of four points need not be coplanar:

 In[5]:=
 Out[5]=
 In[6]:=
 Out[6]=

### Scope (2)

CoplanarQ works with symbolic arguments:

 In[7]:=
 Out[7]=
 In[8]:=
 Out[8]=

CoplanarQ works in higher dimensions as well:

 In[9]:=
 Out[9]=
 In[10]:=
 Out[10]=
