Answer 1

A plane is a two dimensional figure. The intersection of two planes that do not coincide (if it exists) is a line

Answer 2

A plane is a two Dimensional figure.

The Intersection of two planes that do not coincide is always a line.

Consider two planes ,A and B, Following are the possibilities

1. They may be parallel to each other.→→→ No curve obtained

2. The planes A and B can Coincide with each other.→→→Intersection is a plane.

3. The planes A and B are intersecting.→→→→Intersection is a line.
