Answer 3

B or D?

Answer 4

im mostly going with D tbh

Answer 5

Answer 6

however, imagine the planes extend infinitely in all directions (ie each plane is like a piece of paper with an infinite amount of area)

Answer 7

so it could be B?

Answer 8

close, but like I said, the planes extend infinitely in all directions

Answer 9

k so im between A and D

Answer 10

we know its not C or B

Answer 11

So that line segment is really a line



a plane is a flat piece of paper (that doesn't bend at all) and there are no boundaries or limits

Answer 12

Notice how each plane extends infinitely in all directions

Answer 13
