Question

in the cube shown below, which planes intersect? fgj and fgh fij and ghk fgj and hil jkl and fgh

Explanation:

Step1: Analyze the first option

Planes \(FGJ\) and \(FGH\) share the line \(FG\). So they intersect.

Step2: Analyze the second option

Planes \(FIJ\) and \(GHK\) are parallel. They do not intersect.

Step3: Analyze the third option

Planes \(FGJ\) and \(HIL\) are parallel. They do not intersect.

Step4: Analyze the fourth option

Planes \(JKL\) and \(FGH\) are parallel. They do not intersect.

Answer:

FGJ and FGH
