Yes, have you looked at a picture of vertical angles?
Or, you could easily prove it.
EDIT:
Just wanted to let you know, I teach math. Just browsing the answers below mine there are some really uninformed people out there.
Vertical angles are the angles opposite each other when two lines (or line segments) intersect. There will be two sets of vertical angles, an acute pair and an obtuse pair. Except if the lines that intersect happen to be perpendicular, then both sets of vertical angles are right angles.

By "vertical angle", I'm assuming you mean a right angle. All right angles are 90 degrees by definition and, therefore, congruent.

not necessarily... think about how many angles on a unit circle would produce a verticle ray outward from the origin.
so asking about "vertical angles" may be the wrong question. you might need to ponder the definition of an angle a little, before this makes sense.

yes, yes they are:
basically draw a line then put an X thru it, or just come up with a random configuration of lines, this will prove it....
