Answer: 4 points
Explanation:
The minimum number of points needed to define two distinct planes is 4 points. Two distinct planes can be defined by 4 points under the conditions that the two distinct planes intersect at a line, and two points exist on that line that are shared between the planes.
Answer:
One line of intersection (three points of intersection)
When two planes intersect, they don't form points of intersection, but they form a line of intersection.
From equation of a line,
x, y, z are points of intersection
