Question

consider the lines that contain the segments in the figure and the planes that contain the faces of the figure. all angles are right angles. which plane(s) contain point h and appear to be parallel to plane cdh?
plane abc
plane abf
plane ade
plane afh

Explanation:

Step1: Recall parallel - plane concept

In a rectangular - prism (the shape of the aquarium - like figure), parallel planes do not intersect.

Step2: Analyze planes containing point H

We need to find a plane that contains point H and is parallel to plane CDE.
Plane AFG contains point H. And in a rectangular - prism, opposite faces are parallel. Plane AFG is parallel to plane CDE.

Answer:

Plane AFG (It seems there is a mis - naming in the options provided in the original problem, but if we assume the correct plane naming based on the parallel - plane and point - containing criteria, the plane that contains point H and is parallel to plane CDE should be the plane opposite to it. If we assume the correct naming, the answer should be the plane corresponding to the opposite face of CDE that contains H).
