Question

the diagram below is a right rectangular prism. all the angles shown measure 90°. name two segments drawn on the diagram below that are perpendicular.

Explanation:

In a right rectangular prism, adjacent edges meeting at a vertex are perpendicular (since all angles are 90°). For example, segment \( HG \) and \( HD \) meet at vertex \( H \) with a 90° angle, so they are perpendicular. Another example: \( GE \) and \( FE \) meet at \( E \) with a right angle. Or \( KJ \) and \( JI \), etc. (Any two edges meeting at a vertex are perpendicular here.)

Answer:

\( HG \) and \( HD \) (or other valid pairs like \( GE \) and \( FE \), \( KJ \) and \( JI \), etc.)
