Question

Using the diagram, which two planes would intersect in HG ?

Answer 1

Answer: Option 'A' is correct.

Step-by-step explanation:

Since we have given that

The figure of cuboid is given in the question.

we need to find the two planes that would intersect in HG.

B. ABCD and EFGH

EFGH contains HG whereas ABCD does not.

So, it can't get intersected in HG.

C. BCEF and ABCD

HG is not contained in both the planes.

D. ADHE and ABEF

HG is not contained in both the planes.

A. EFGH and CDHG

Both the planes contain HG.

so, it would intersect in HG.

Hence, Option 'A' is correct.

Answer 2

Answer:

A. EFGH and CDHG  

Step-by-step explanation:      

We have been given a diagram and we are asked to find which of the given planes would intersect in HG.

We can see from our diagram that HG is the common side for planes EFGH and CDHG. This means that planes EFGH amd CDHG intersect in HG.

Therefore, our answer will be planes EFGH and CDHG and option A is the correct choice.
