nalyzing Intersections of Lines and Planes The left vertical plane intersects the horizontal plane at line x. The right vertical plane intersects the horizontal plane at line w. Line y intersects line x at point B and intersects line w at point A. Line v extends vertically through the horizontal plane. Line z extends horizontally through the left vertical plane. Point C is on the lower half of the left plane is on line z. Point D is on line z but not on the left vertical plane. Point E is on the lower half of the right plane. Use the given diagram to answer the question. Which line is the intersection of two of the planes shown? Which line intersects one of the planes shown? Which line has points on three of the planes shown?
