Here is the diagram showing five labeled points. The points $A$, $B$, $C$, and $D$ are coplanar (lying on the same plane), while point $E$ is not coplanar with the others, as it is positioned above the plane containing the first four points.

3. What are some applications of non-coplanar points in geometry?
4. How can vectors be used to prove that points are coplanar?
5. Can more than four points be coplanar in 3D space?
6. What is the significance of the Z-coordinate in determining coplanarity?
7. How would the equation of the plane containing points $A$, $B$, $C$, and $D$ look?

Tip: When analyzing points in 3D space, checking the determinant of the matrix formed by their position vectors can help determine if they are coplanar.
