They are equal opposite vertical angles and if the lines are perpendicular to each other then 90 degree angles are formed.
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.
Nonadjacent angles formed by the intersection of two lines are referred to as vertical angles. When two lines cross, they create two pairs of vertical angles that are opposite each other. Vertical angles are always equal in measure, providing a fundamental property in geometry. These angles are not beside each other, which distinguishes them from adjacent angles.
They are said to be perpendicular. Or, if you wanted an example of a pair of such lines, one example is a plus sign.
Vertical angles are congruent when two lines intersect. At the point of intersection, they form two pairs of opposite angles that are equal in measure. This congruence holds true regardless of the angles' specific measurements, as long as they are formed by the intersection of two lines.
Adjacent angles
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.
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
Two intersecting lines form four angles. Each pair of opposite angles created by the intersection is equal, resulting in two pairs of vertical angles. These angles sum up to 360 degrees around the point of intersection.
