When two nonvertical straight lines intersect they form two congruent pair of nonadjacent angles, which are called the vertical angles (or vertical opposite angles).
So that one of the three vertical angles is 30 degrees, and the other two angles have a measure of 150 degrees each, since they are adjacent to a 30 degrees angle.
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.
When 2 straight lines intersect vertical opposite angles are equal and the 4 angles created add up to 360 degrees
Equal vertical opposite angles are created when straight lines intersect each other
They are angles formed when two straight lines intersect: they are on opposite sides of the point of intersection.

Vertical angles
Equal angles.
Perpendicular lines that that intersect at 90 degrees are right angles.
Equal angles.
They are straight lines that intersect each other at right angles or 90 degrees.
