Question

in the cube shown below, which planes intersect? ghk and gjk gjk and hil ghk and ljm klm and ghi

Explanation:

Step1: Recall plane - intersection concept

In a cube, two planes intersect if they are not parallel.

Step2: Analyze each option

• For GHK and GJK: They share the line GK, so they intersect.
• For GJK and HIL: GJK is a face - like plane and HIL is a non - parallel plane that will intersect GJK.
• For GHK and LIM: These two planes are parallel and do not intersect.
• For KLM and GHI: These two planes are parallel and do not intersect.

Answer:

GHK and GJK, GJK and HIL
