Vertical AngleThey form vertical angles
Vertical angles. These are two angles who, together, form two pairs of opposite rays. This means that these two angles form two lines that intersect. These angles have to be equal.
yes
yes, intersecting lines form two pairs of congruent angles
If the two lines are parallel, then you get 4 pairs of vertical angles. If the two lines are not parallel, then we get 6 pairs of vertical angles.
Vertical angles
equal vertical angles
Two pairs of opposite equal angles are formed
Vertical-A+I believe the answer would be 2 ninety degree angles
Those are "vertical" angles, even if there's nothing vertical about them.
Two pairs of vertical angle formed by intersecting lines is a plus sign or an x. something that looks like this, but with the lines completely touching: +x
Vertical opposite equal angles

Eight.
Angles that are pairs of opposite and congruent lines formed by intersecting lines are intersections
They are equal vertical opposite angles or 2 pairs of equal angles.
