The top and bottom angles - the angles that are between the pairs of congruent sides. They are opposite each other and not necessarily congruent.

Not necessarily
A quadrilateral that could have a 45-degree vertex angle is a kite. In a kite, the two pairs of adjacent sides are congruent, and one pair of opposite angles is congruent. Therefore, if one of the angles is 45 degrees, the opposite angle would also be 45 degrees. This makes a kite one of the quadrilaterals that could have a 45-degree vertex angle.
A kite has 4 right angles (all angles of the kite are right angles), since the kite is parallel. If the kite was cyclic, then 2 right angles. And if normal kite, then 0 right angles.
If two angles do not have a common vertex they cannot be adjacent angles.
Angles that have a common side between them and a common vertex are called adjacent angles.
