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.

A kite (quadrilateral) has a pair of opposite angles which are the same measure. The diagonals are perpendicular, so you can divide the kite into four right triangles, and solve for those if you're given some dimensions. The diagonal, which connects the two congruent (same) angles, will be cut in half (bisected) by the other diagonal.
If two angles do not have a common vertex they cannot be adjacent angles.
Adjacent angles are defined as angles that share a side and a vertex point. A vertex is a corner point.
The nonvertex angles of kite are congruent, and are the two angles that appear closer together.
Adjacent angles have a common side and a common vertex.
Kite is a quadrilateral in which 2 pairs of opposite angles are equal .
Yes.
Adjacent angles have a shared vertex.
