They are the angles opposite each other when two lines intersect.
They are simply called opposite angles.
When 2 lines intersect, 4 angles are formed. The angles that are directly opposite to each other are called opposite angles.
Vertical angles
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.
