usually they are just called vertical angles
Vertical Angles
No vertical angles are across from each other & adjacent angles are beside but opposite from each other.
Draw to lines intersecting each other. The angles across from each other will be both congruent and adjacent
Vertical angles occur when 2 angles are directly across from each other and are congruent.
Vertically opposite angles, or vert. opp. angles for short.

Opposite angles are angles across from each other in intersecting lines. For example, see the figure below:a-> X

When two lines intersect, the angles across from each other are called vertically opposite angles, or just opposite angles. Opposite angles are equal to one another. See 'related links' below.
Angles opposite of each other are typically referred to as "opposite angles" or "vertical angles." These angles are formed when two lines intersect, creating pairs of angles that are across from each other. Vertical angles are always equal in measure, meaning if one angle is 40 degrees, the opposite angle will also be 40 degrees.
The term parallelogram refers to a four sided geometrical figure (in other words, a quadrilateral) in which there are two sets of parallel sides. The angles can vary; they can be right angles, or they can be acute or obtuse angles, as long as there are two sets of parallel sides. Angles are not said to be vertical to each other. Angles can be perpendicular to each other, but not vertical or horizontal. If angles are perpendicular, then they are right angles, in other words, 90o angles. Lines can be vertical, but angles can't.
It might be a right angle not really sure
The opposite angles are equal angles. The adjacent angles are supplementary (add to 180°)
