All four angles in a rectangle are 90 degrees. In any quadrilateral the sum of all four angles is 360 degrees.
It is one of the four corners of a rectangle.
90 degrees.
A square and a rectangle.
A rectangle, by definition, has four right angles, each measuring 90 degrees. If a rectangle were to have "no angle," it would not meet the criteria of being a rectangle. Additionally, if "same size" refers to equal dimensions, a rectangle maintains its properties regardless of size, as long as it retains its shape with right angles. Therefore, a rectangle cannot exist without angles.

Each angle of a rectangle is equal to the angle opposite.

A rectangle is not an angle.

Yes, a rectangle is a special kind of parallelogram - one that has a right angle. (You can prove that if it has one right angle all angles are right.)
If you mean if one of the angles is a right angle, then yes, because a rectangle is the only option left if it is to remain a parallelogram.
No, a rectangle cannot have an obtuse angle. By definition, a rectangle is a quadrilateral with four right angles (90-degree angles). An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees. Therefore, in a rectangle, all angles must be right angles, making it impossible for an obtuse angle to exist within a rectangle.

A rectangle can have only one obtuse angle, and lots of rectangles do not have an obtuse angle at all. So it is either none or one.
