a rhombus, a quadrilateral without right angle, a quadrilateral with equal opposite parallel sides but no right angles
Quadrilateral means four sides. Four right angles and four sides is a rectangle and if the sides are equal length it is a square.
Assuming that ALL its sides are equal, it must be a square.
It is a parallelogramIf one of the angles is a right angle (then they all are) and the quadrilateral is a rectangle.If both pairs of sides are equal in length (but none of the angles is a right angle) the quadrilateral is a rhombus.If the sides are equal and one of the angles is a right angle, the quadrilateral is a square.
A rhombus

that's a rhombus with no right angle

There is no such thing as a regular trapezoid. REGULAR implies that all sides and all angles are equal. If that is the case, with a quadrilateral each angle would be 90 degrees, none would be 50.
Quadrilateral means four sides. Four right angles and four sides is a rectangle and if the sides are equal length it is a square.
