A trapezium (US trapezoid).
a Trapezoid
You call it a parallelogram.
Well, you are supposed to call an irregular quadrilateral an IRREGULAR QUADRILATERAL. Haha. There really isn't any name for a regular quadrilateral. You just call it a quadrilateral or whatever the shape is. You could call it a REGULAR QUADRILATERAL.
There is no specific name. Irregular is not enough because a rectangle is irregular.
a square or rectangular are the first things that came to my mind
i think you call it a irregular quadrilateral
Quadrilaterals usually have special names only if they DO have parallel sides, or some other special property. You might just call it "quadrilateral", or "a quadrilateral with no parallel sides".
a Trapezoid
Oh, dude, that's an easy one. So, like, a quadrilateral with exactly 1 pair of parallel sides is called a trapezoid. It's like a fancy word for a shape that's a bit lopsided, you know? So, yeah, next time you see a wonky four-sided figure, just be like, "Hey, that's a trapezoid!"
You call it a parallelogram.

A quadrilateral with exactly one pair of parallel sides is known as a trapezoid. In a trapezoid, one pair of opposite sides are parallel, while the other pair of opposite sides are not. This unique characteristic of having only one set of parallel sides distinguishes a trapezoid from other quadrilaterals like rectangles or parallelograms. The parallel sides are called the bases of the trapezoid, while the non-parallel sides are referred to as the legs.
A quadrilateral is a polygon with 4 sides. ... Definition: A parallelogram is a quadrilateral where both pairs of opposite sides are parallel. We use the symbol to represent a parallelogram.
