All trapezoids must be quadrilateral. And, as the name suggests a quadrilateral has four sides.
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.)
No. A quadrilateral only must have four sides; those four sides can be arranged on any angle that permits the four sides to also have four angles.
No: the very nature of the word "quadrilateral" tells you that there must be four sides. "Quad" is a prefix meaning "four".
a square or a rhombus
There is specific name for such a shape.
No, a quadrilateral must have 4 sides. If it is a proper quadrilateral it must have 4 sides of equal length but if it is an irregular quadrilateral it must have 4 sides but not have equal sides. An example of a quadrilateral could be a square. A pentagon on the other side must have 5 sides.

An impossibility. By definition a quadrilateral with 4 congruent sides must have congruent adjacent angles.
a square or a rhombus
No; the definition of a quadrilateral is a four-sided polygon, thus, it must have 4, and only 4, sides.
Four straight sides, all in the same plane, meeting pairwise at four vertices.

Quadri means four. Lateral means sides. A quadrilateral has four sides.
