They would probably be the two pairs of angles in the parallelogram or kite base of a quadrilateral based.
Two pairs of adjacent angles are formed when two lines intersect each other.
There are two pairs of congruent base angles in an isosceles trapezoid.
Two pairs.
Vertical-A+I believe the answer would be 2 ninety degree angles
Yes.
Two pairs of opposite equal angles are formed
Two pairs of adjacent angles are formed when two lines intersect each other.
They are equal vertical opposite angles or 2 pairs of equal 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.
equal vertical angles
There are two pairs of congruent base angles in an isosceles trapezoid.
There are 56 pairs of congruent angles.
Yes, they are formed. So what is the question?
Two pairs.
Vertical opposite equal angles
Vertical-A+I believe the answer would be 2 ninety degree angles
Such angles are called vertically opposite angles.
