Question

Which describes the intersection of planes A and B?

A) line CD
B) line ED
C) point C
D) point D

Answer 1

You're looking for points that are both on plane A and plane B. Also, the intersection of two planes is a line. So all answers with just a point or point C in them are incorrect. That leaves line ED. E and D are both in plane A and B.

Answer 2

The line ED describes the intersection of the planes A and B.

What is a plane?

'In mathematics, a plane is a flat, two-dimensional surface that extends indefinitely.'

According to the given problem,

The points E and D both lie on Plane A as well as on Plane B.

Therefore, the line connecting the points E and D which is the line ED, is the line common to both A and B.

Hence, we can conclude, the line ED describes the intersection of planes A and B.
