"Concave quadrilateral" or "arrowhead" or "dart."
If you need just one answer for a test or a homework assignment, I would go with "concave quadrilateral" as the best asnwer. Hope that helps!

are you looking for a trapezium?
In geometry, a trapezium is the British name for a quadrilateral with a pair of parallel sides, and the American name for a quadrilateral without parallel sides..
A trapezoid (in North America) or trapezium (in Britain and elsewhere) is a quadrilateral. Some authors define it as a quadrilateral having one pair or two parallel sides, so as to include parallelograms
In geometry, a rhomboid is a parallelogram in which adjacent sides are of unequal lengths and angles are oblique.
A shape like a rhomboid with sides of equal length (equilateral) is a rhombus.
A shape like a rhomboid with right angled corners is a rectangle.
