so he is right lol

Answer 16

no he's wrong as he believes they're lines and not planes. He picked the right answer but got super lucky. Anyways to see this, take two papers and put them next to each other

Answer 17

or better yet grab a book, if you imagines that the front cover extended forever and the back extended forever and you opened it so that it looked like this

Answer 18

you can see that the place of intersection would be the seam of the book

Answer 19

in this case the seam of the book is your segment MN
