When two lines intersect, forming an "X", the vertical angles are opposite each other. You will have 2 sets of vertical angles; the top and bottom, and the right and left sides. They are always congruent.

If you draw two line segments that intersect each other, you have drawn two sets of vertical angles.

Vertical angles share only one point in common: their vertices, which is the point at which the two line segments intersect. You could say that vertical angles are opposite each other. The important thing to know is that vertical angles are always congruent, i.e. they have the same angle measurement.
