Question

in the cube shown below, which planes are parallel? ij m and hdj hkl and ij m hkl and lmn ij m and jkn

Explanation:

Step1: Recall parallel - plane concept

In a cube, opposite faces are parallel planes.

Step2: Analyze each option

• Option "IJ M and HDJ": These planes are not opposite and intersect.
• Option "HKL and IJ M": These planes are not opposite and intersect.
• Option "HKL and LMN": These planes are adjacent and intersect.
• Option "IJ M and JKN": These planes are opposite. In a cube, the planes formed by non - adjacent vertices on opposite sides are parallel.

Answer:

IJ M and JKN
