Opposite angles are equivalent when formed by two intersecting lines
verticle angles
Vertical angles are a pair of non-adjacent angles formed by the intersection of two lines. They are congruent, meaning they have the same measure. In other words, vertical angles are opposite each other when two lines intersect, and their measures are equal.
Vertically opposite.
Perpendicular lines.
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.
They are angles formed when two straight lines intersect: they are on opposite sides of the point of intersection.
They are said to be perpendicular. Or, if you wanted an example of a pair of such lines, one example is a plus sign.
Adjacent angles
Opposite angles are equivalent when formed by two intersecting lines
Angles that are pairs of opposite and congruent lines formed by intersecting lines are intersections
If the two lines form an X then each angle directly across from another is congruent or equal to that angle.
Equal opposite angles.
An angle is formed by the intersection of two straight lines. If the lines are perpendicular, they will form right angles.
Perpendicular is when opposite angles that are formed when two lines intersect and are congruent called?
