If two angles are vertical then they are congruent.
Vertical angles can be supplementary angles if the lines are perpendicular and then both of the vertical angles would be 90 digress.
No, because by definition, vertical angles are not adjacent angles. Hope this helps
The Vertical Angles Theorem says that a pair of vertical angles are always congruent.
Vertical angles are equal in measure and are formed when two lines intersect. Complementary angles, on the other hand, add up to a total of 90 degrees. They are not directly related, but if two lines intersect and form vertical angles, then the angles adjacent to the vertical angles will be complementary.
Well it could be complementary or supplementary because they don't have to share a vertex yet I think you mean something like the vertical angle. You can go research vertical angles. I'll give you a link for the vertical angles. http://www.mathsisfun.com/geometry/vertical-angles.html
Geometry is the branch of mathematics that is concerned with the properties and relationships of points, lines, angles, curves, surfaces, and solids.
not all congruent angles are vertical angles. Vertical angles must share a vertex.
Generally vertical angles are the angles opposite each other when two lines cross. "Vertical" in this case means they share the same Vertex (corner point), not the usual meaning of up-down.

Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.

No they are not because adjacent angles are on the same side while vertical angles are on the opposite therefore vertical angles are non adjacent.
which pair of angles in the figure below are vertical angles ?
There are four right angles in a square or rectangular geometry
