Yes, the intersection of 2 planes is a line.
No, planes intersect at a line.
An edge is the curve formed where two of the planes defining [bordering] the 3D shape meet. It is often a straight line where the planes defining the shape meet but, as in the case of a hemisphere, an edge could be a circular boundary where the flat face meets the curved face.
ONLY a line can be formed by the intersection of two planes...and always.
Yes, it is possible for three distinct planes to intersect at a line.
Two planes intersect at a line. The line where they intersect pertains to both planes. In the same manner, if infinitely many planes intersect each other at the same line, then that line pertains to the infinitely many planes.
Two planes intersect at a line
Yes, the intersection of 2 planes is a line.
A line is the intersection of two planes. The angle between the planes is called the "dihedral angle".
No, planes intersect at a line.

A line. When two planes intersect, their intersection is a line.
Check out the floor and one wall of the room you're sitting in right now, especially the place where they meet.
The intersection of two distinct planes is a line. The set of common points in the line lies in both planes.
An infinite number of planes. Picture a line and now picture planes going in every direction through the line,
ONLY a line can be formed by the intersection of two planes...and always.
Yes, it is possible for three distinct planes to intersect at a line.
