Two intersecting rays form an angle. Without two rays you do not have an angle.
The angle is called the reflected angle.
as long as they intersect.
The questions doesn't make sense. An angle isn't a parallelogram. Parallelograms are types of shapes while an angle are to rays.

two rays make up an angle, so the rays are the sides of the angle.
Two rays with the same origin make an angle.
2 rays
The angle is called the reflected angle.
as long as they intersect.
any rays that intersect will form 4 angles
Two and only two rays having the same end points are in an angle.
Depends on how many rays you combine but, normally only 1 angle.
Reflected rays are equal to the angle of incoming rays.
