Adjacent angles
If the two lines form an X then each angle directly across from another is congruent or equal to that angle.
They are angles formed when two straight lines intersect: they are on opposite sides of the point of intersection.
Perpendicular Lines form right angles at their point of intersection
In mathematics, particularly in geometry, "vertically opposite" refers to pairs of angles that are formed when two lines intersect. These angles are opposite each other and are always equal in measure. For example, if two lines cross, the angles formed at the intersection can be categorized into pairs of vertically opposite angles, which share a common vertex but do not share a common side.
Perpendicular lines
They are equal opposite vertical angles and if the lines are perpendicular to each other then 90 degree angles are formed.
They are said to be perpendicular. Or, if you wanted an example of a pair of such lines, one example is a plus sign.
If the two lines form an X then each angle directly across from another is congruent or equal to that angle.
Vertical equal opposite angles are formed when lines intersect each other.
Vertical equal opposite angles are formed when lines intersect each other.
If I understand the question: Either pair of opposite angles formed by the intersection of 2 lines.
Perpendicular if they form right angles if not they form vertical opposite equal angles
They are angles formed when two straight lines intersect: they are on opposite sides of the point of intersection.
When two straight lines intersect they form 360 degees with opposite angles being equal.
