not all congruent angles are vertical angles. Vertical angles must share a vertex.
Vertical angles must be congruent so if they are complementary, they must be 45 degrees to be complementary.
Yes, the opposite rays of vertical angles are always coplanar, so the angles are as well.
In a Linear Pair the 2 angles add up to 180 degrees while Vertical Angles are just 2 vertical angles that are congruent.
yes or no

No.
Equal angles.
Vertical, possibly!
Vertical angles must necessarily be congruent, however congruent angles do not necessarily have to be vertical angles. An example of congruent angles which are not vertical angles are the 3 interior angles of an equilateral triangle. These angles do not share the same vertex yet they are congruent.
Equal angles.
C. have the same vertex. done D. be congruent
Vertical angles are always, by definition, congruent. Note: If the two vertical angles are right angles then they are both congruent and supplementary.
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 they are not because adjacent angles are on the same side while vertical angles are on the opposite therefore vertical angles are non adjacent.
