A rectangle has 4 right angles and 2 pairs of parallel sides.
A right angle in a 90 degree angle.

I think what you are asking is the following:
If a quadrilateral (four-sided polygon) has a right angle and one pair of parallel sides is it necessarily a rectangle.
The answer is NO. A trapezoid can have a right angle and one set of parallel sides and not be a rectangle (draw the outline of a shed with a slanting roof!).
By definition a rectangle is a quadrilateral with four right angles.
You could also define it as a quadrilateral with at least one right angle and two pairs of parallel sides.
Your question is designed to make you think, to draw diagrams and experiment with them, to gain insights into geometry and how to learn it. The question is not designed just to provide an answer.
Anyone can regurgitate answers. Learning to think is more difficult, but worth the effort.

A rectangle has 2 parallel sides, the lenght and the width. All the corners are 90°, making them right angles.

A regular trapezium has two sides parallel and no right angles. It looks like a pyramid with the top cut off.

yes it does. Because there are two parallel sides and four right angles.
