A quadrilateral has four angles. There are always the same number of angles as there are sides, so since a quadrilateral has four sides it must also have four angles.A quadrilateral doesn't "do" any angles. However, it has four angles. (If that is what you wanted to know.)

A square and a rhombus both have 4 congruent sides but a square has 4 equal interior right angles whereas a rhombus has 2 obtuse and 2 acute interior angles

Angles that are congruent and supplementary must be right angles.

No because the total angles in a quadrilateral must not exceed 360 degrees.

An impossibility. By definition a quadrilateral with 4 congruent sides must have congruent adjacent angles.

For the quadrilateral to be a parallelogram, both pairs of opposite angles must be congruent.

No. If the diagonals of a parallelogram are congruent then it must be a rectangle (or square).

A rhombus is a quadrilateral whose four sides are congruent. Squares are a type of rhombus with congruent angles. Since there are 4 contruent angles, they must all be right angles.So any quadrilateral that is equilateral is a rhombus and any rhombus with 4 right angles is a square. Every rhombus is a parallelogram because the opposite angles of a rhombus are congruent. Also, the diagonals of a rhombus are perpendicular.

4 right angles, by definition, are four angles of the same measure, and therefore must be congruent angles.
