360 degrees
the two adjacent angles formed by the intersecting lines will equal 180 degrees.
Equal opposite angles.
equal vertical angles
They are of EQUAL size, and described as 'Vertically Opposite'.
Opposite angles are equal. Adjacent angles add up to 180 degrees.
Two angles that aren't adjacent but are formed by intersecting lines are called vertical angles. Their angle measures are always equal.
They're just called opposite angles, and they are congruent, or their measures are equal.
the two adjacent angles formed by the intersecting lines will equal 180 degrees.
no unless they're perpendicular
They are equal vertical opposite angles or 2 pairs of equal angles.
Equal opposite angles.

equal
I assume you are asking what such angles are called. The answer is, vertical angles.
Opposite angles are equal. Adjacent angles add up to 180 degrees.
Yes, if they intersect at right angles.
