Answer:
(A) E
(B) FGI
(C) D and E collinear .
(D) 0
Explanation:
(A)
From the given graph it is clear that line l and m intersect each other at point E.
Therefore E is the intersection of l and m.
(B)
A plane name is the set of any three non-collinear points, which are lie on the plane .
Points F, G and I lie on the plane Q.
Therefore, FGI is another name for plane Q.
(C)
If two point lie on the same line then they are collinear.
If two point lie on the same plane then they are coplanar.
From the given figure it is clear that point D and E are on different plane but lie on the same line.
Therefore, the point D and E are collinear.
(D)
From the given figure it is clear that the plane P and Q are parallel.
Parallel planes never intersect each other.
Therefore, plane P and Q never intersect each other.
