There are only two proper names for the shape: trapezoid (US) and trapezium (rest of the English speaking world - which is very much larger). Any other names are too broad and would include lots of shapes that are anything but trapezoids. A trapezoid is a polygon but so is any plane shape with 3 or 5 or more straight sides. A quadrilateral is better, but that terms includes (for example) a square which is certainly NOT a trapezoid.
Oh, dude, let's see... you can call a trapezoid a "four-sided polygon with one pair of parallel sides," or you could spice it up and say it's a "quadrilateral with one set of parallel lines." Some people might even call it a "quadrangle with slanted sides." Like, there are so many ways to describe this shape, it's almost like giving it a new identity every time you talk about it.
In geometry, a trapezoid is a quadrilateral with at least one pair of parallel sides. Some alternative names for a trapezoid include trapezium (more commonly used in British English), irregular quadrilateral, convex quadrilateral, and right trapezoid (if one angle is a right angle). Additionally, a trapezoid can be referred to as a trapezium in American English, a trapeze, or a trapezoid.
All the names to classify a trapezoid are a trapezoid and a quadrilateral.
A trapezoid in the UK is a trapezium which is a 4 sided quadrilateral with 1 pair of opposite parallel sides of different lengths.
A trapezoid, a trapezium, an isosceles trapezoid or trapezium and it is a 4 sided quadrilateral.
quadrilateral , polygon, and probably trapezoid?
A trapezoid can also take the form of an isosceles trapezoid

In the US it's known as a trapezoid in the UK it's known as a trapezium but they are both quadrilaterals.

ANSWER: A parallelogram (It can also be called a trapezoid) ... but a trapezoid is not a parallelogram!
A trapezoid can also take the form of an isosceles trapezoid
