A geometric figure with four sides is a quadrilateral. This definition is irrespective of length of sides.
Moreover, you can divide this category in to following sub- categories
1. Square :A square is a quadrilateral with four equal sides and four equal right angles.
2. Rectangle : A rectangle is a quadrilateral With four equal right angles, and two sets of parallel opposite sides that are equal.
3. Rhombus : A Rhombus has got 4 sides of equal length and opposite sides are parallel and angles are equal.
3. Parallelogram :A parallelogram is a quadrilateral that has two pairs of opposite sides that are parallel and equal to one another. It differs from a rectangle in that its angles are not right angles. A rhombus is an equilateral parallelogram, with all sides equal.
4. Trapezium(trapezoid) : A trapezoid is a quadrilateral with two opposite sides parallel but not equal.
5. Kite : A kite has got two pairs of sides next to each other that have equal length. But none of the sides are parallel.
I hope this clears your idea in wider sense. Any time you want to classify a geometric figure with 4 sides, just look in this and you will know what should you call that figure.
All the best

That's like asking, "when is a square not a square".
The least restrictive multi-sided shape with
straight sides is a polygon.
A polygon with 4 sides is a quadrilateral.
A quadrilateral with one pair of parallel sides is a trapezoid.
A trapezoid with 2 pairs of of parallel sides is a parallelogram.
A parallelogram with 1 right angle is a rectangle.
A rectangle with 2 equal adjacent sides is a square.

If you started with a square and then made one of the sides longer than the other, you would have what is called an isosceles trapezoid. Clear and simple.

There's no such square! A square, by definition,
has all 4 sides the same length.

A 2d shape with three equal sides and one longer one is called a trapezium or trapezoid. It is not a square though.

Trapezoid
The sides, Two of which are parallel and two of which are non parallel. The parallel side of the Trapezoid are called bases and the non parallel are called side legs

In a square all sides are equal. It would be a quadrilateral.
