trapezium
Parallelogram, Rectangle, and Isosceles Trapezoid, opposite sides are congruent.
At least one pair, or one pair? If it is one pair, then it depends if the shape is regular or irregular.

a square
No.
No, because all quadrilaterals have 4 straight sides.
yes
A trapezoid (or trapezium) has at least one pair of parallel sides.If you asked, "Name all the types of quadrilaterals which have at least one pair of parallel sides?", I would answer: Trapezoid, rhombus, parallelogram, rectangle and square.
Most times but not always as for example a trapezoid would be an exception unless it was an isosceles trapezoid
A trapezium and a parallelogram are both quadrilaterals with at least one pair of parallel sides.
rhombus * * * * * The correct answer is a parallelogram, of which a rhombus is a special case.
No. An example of a quadrilateral that doesn't have a pair of parallel sides is a kite.
Pull out three socks. You will have at least one pair that matches.
Trapezium
Maybe all the ones you talk about in school have at least one pair of equal sides, but there are an infinite number of other quadrilaterals that have no equal sides. Take four sticks ... 1 foot, 2 feet, 3 feet, and 4 feet. There's no problem gluing their ends together to make an ugly, out-of-shape quadrilateral.
