They are called vertical angles
A pair of opposite equal angles are formed when two lines intersect each other.
Intersecting lines form two sets of angles. The angles opposite each other are always equal.

intersecting lines are lines that block each other.
Perpendicular lines intersect each other at 90 degrees
Perpendicular lines are a possibility. This will only happen if the intersecting lines are exactly 90 degrees from each other.
The definition that best describes vertical angles is C: A pair of opposite angles formed by intersecting lines. Vertical angles are the angles that are across from each other when two lines intersect, and they are always equal in measure.
Intersecting lines are lines that meet at a point. In other words lines that cross each other (like an X).
Either intersecting lines or perpendicular lines
The addition sign is formed by two intersecting lines, as is the cross. The two lines are perpendicular to each other.
