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
Lines that intersect to form right angles at their point of intersection have slopes that are negative reciprocals.
Perpendicular lines
They are said to be perpendicular. Or, if you wanted an example of a pair of such lines, one example is a plus sign.
They are equal opposite vertical angles and if the lines are perpendicular to each other then 90 degree angles are formed.
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.
