Maybe I took it wrong, but my impression of the original question was that the TS wanted to know how come planets form triangle instead of a straight line. On other words, why planets in Solar system are not in the same orbit plane?
This problem is not as trivial as it might seem. Look at the rings of Saturn, for instance. It consists of billions of ice pieces all going in virtually the same plane. On the other hand, if you look at the planets' orbit planes - those are noticeably inclined, for up to 7 degrees for Mercury.
