A pair of intersecting lines form adjacent and opposite angles. So the answer to the question is an opposite angle.

Verticle angles
When two lines intersect four angles are formed. Adjacent refers to angles that are next to each other so non adjacent refers to the ones opposite each other. They will have equal angles. Two adjacent angles in this situation will have a sum of 180 degrees.
two adjacent angles formed by two intersecting tines are
Such is called an exterior angle. A useful theorem is that an exterior angle is equal to the sum of its non adjacent interior angles.
Well, they're called vertically adjacent angles. They have the property that they are supplementary, because the non-adjacent sides form a straight line.
A supplementary angle can be either adjacent or non-adjacent.A linear pair must be adjacent and is never non-adjacent.NOTE: They both add up to 180°.
Theorem: An measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.An exterior angle is formed by one side of a triangle and the extension of an adjacent side of the triangle.In the triangle at the right,
That's a "straight" angle ... 180 degrees. If the vertex isn't marked, it looks like an innocent straight line, and you'd never know that it's an angle at all.
That would be a right angle: The measure of complementary angles adds up to 90 degrees. Adjacent angles are angles that share one common side and one common vertex, but no common interior points (the angles don't overlap). The non-common sides of two adjacent angles are the two "outside" sides (the unshared sides). Two adjacent and complementary angles would form a right angle split by a ray/line, and not necessarily bisected (perfectly divided in half).
The alternate interior angle theorem states that when two parallel lines are cut by a transversal, the alternate interior angles formed are congruent. In other words, if two parallel lines are crossed by a third line, then the pairs of alternate interior angles are equal in measure.
Whenever two lines intersect, vertical angles refers to the angles opposite each other
