Answer:
See below.
Step-by-step explanation:
There are 3 planes:
1) A vertical plane at the left that contains points B and C.
2) A vertical plane at the right that contains points A and E.
3) A diagonal plane (close to horizontal, but not quite) that contains points A and B.
The intersection of the plane containing points B and C with the plane containing points A and B is line x.
The intersection of the plane containing points A and E with the plane containing points A and B is line w.
Line y lies on the plane that contains points A and B.
Line z lies on the plane that contains points B and C.
Line v intersects the plane that contains points A and B.
Now we look at the three questions:
1) Which line is the intersection of two of the planes shown?
There are 2 correct answers: x, w
2) Which line intersects one of the planes shown?
v
3) Which line has points on three of the planes shown?
y
