Asked by Shadow

Earlier you told me "hold a pencil up. A real pencil. I bet you can make perpendiculars in many directions, because the pencil is in a three dimensional space". Could you explain to me what do you mean by this? I try holding up a pencil and doesn't see anything.Thanks

No matter which way you old it, it is perpendicular to some plane.

Hold a book at different angles. Can you hold the pencil in such a way that it's perpendicular to the book, no matter which way you old it?

Yes.

the reason it is three dimensoinal, is so that it can go in every simngle way possible. i know that it seems like a lot at first but it is kind of simple...
