Question

the diagram below is an oblique, or slanted, rectangular prism. not all angles shown are 90°. complete the following sentence.
answer
attempt 1 out of 2
plane hdc
options: are parallel, are perpendicular, intersect but arent necessarily perpendicular

Explanation:

To solve this, we analyze the properties of an oblique rectangular prism:

Step 1: Recall Prism Properties

In a rectangular prism (oblique or right), opposite faces are parallel. Plane \( HDCG \) and plane \( ABFE \) are opposite faces of the prism.

Step 2: Determine Relationship

Since it’s a rectangular prism, these two planes (being opposite faces) must be parallel. They don’t intersect (so not "intersect but aren’t perpendicular") and aren’t necessarily perpendicular (as it’s oblique, angles aren’t all \( 90^\circ \)).

Answer:

are parallel
