I thought it was the second one... but it's not.

Answer 3

Answer 4

the First one?

Answer 5

yes, think of plane as a flat surface

Answer 6

Ok, how would the second one not be true?

Answer 7

then u wil see that they intersect all the way along PQ

Answer 8

second one is not correct, becoz it says they intersect ONLY at two points

Answer 9

the two planes intersect all the way ALONG PQ
