What plane contains points E, F, and H?

The plane containing points E, F, and H could be named as plane EFH or plane FHE or any other combination of the three points. The name of the plane is arbitrary and does not affect its actual properties.

To determine the plane that contains points E, F, and H, we need to use the concept of collinearity. If three points are collinear, they lie on the same line. However, if they are not collinear, they define a plane.

So, let's check if points E, F, and H are collinear:

1. Calculate the slopes of the line segments EF, EH, and FH.
- If the slopes are equal, E, F, and H are collinear.
- If the slopes are not equal, E, F, and H define a plane.

2. If the slopes are not equal, the plane that contains points E, F, and H can be determined by:
- Finding the equation of the plane using the coordinates of the three points.
- Or using the normal vector of the plane if it is provided.

Please provide the coordinates of points E, F, and H to proceed further.
