When funneling our mixure we were told to tear a corner of the filter paper, or side, however you want to view it, and then put it in the funnel. Why is it that you tear the corner?

how to fold a filter paper ?
Fold the filter paper in half, again fold the filter paper to within about 10° of a 90° fold, tear off the corner unequally, and open.
why do we tear off the corner unequally ?
The tear enables a close seal to be made across the paper's folded portion when placed in a funnel.

This was probably to make it stay in a cone shape. Another way of doing this would have been to wet it after putting it in the funnel.
