a trapezoid
That shape would be a trapezoid.
trapazoid
An isosceles trapezoid would seem to fit the given description.
irregular trapezium
A trapezium (has only one pair of unequal parallel lines).
A trapezoid has 4 sides, 2 acute and 2 obtuse angles, and only one pair of parallel sides
its a shape
A shape that has 2 right angles, only 1 set of parallel sides, and no lines of symmetry is a right trapezoid (or right-angled trapezium). In this trapezoid, the two non-parallel sides are not equal in length, contributing to the lack of symmetry. The right angles are formed between one of the parallel sides and one of the non-parallel sides.
It is a trapezoid and its other 2 angles are obtuse and acute
A shape with no right angles and one pair of parallel lines would be called a trapezoid in the USA, and a trapezium in Britain.
