a trapezoid
A geometric shape with only one set of parallel sides is a trapezoid.
A trapezium. It has one set of parallel sides. It has four sides.
A general trapezium, and selected versions of polygons with 5 or more sides.
A square is a regular polygon with two sets of parallel sides. A parallelogram is an irregular polygon with one set of parallel sides. A rhombus is an irregular polygon with two sets of parallel sides. A rectangle is an irregular polygon with two sets of parallel sides. *Note - a regular polygon is a shape in which all sides are equal in length and all angles are equal in measurement.

trapezoid
The shape that has only one set of parallel sides and two right angles is a trapezoid (or trapezium in some regions). In this case, it specifically refers to a right trapezoid, which has two right angles. The other two angles can be acute or obtuse, but the defining feature is the single pair of parallel sides.
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.
A trapezoid perhaps?
A geometric shape with only one set of parallel sides is a trapezoid.
A right trapezium.
It is a trapezoid and its other 2 angles are obtuse and acute
The description given fits that of a trapezoid
A shape with four sides and one set of parallel lines is called a trapezoid (or trapezium in some regions). In this shape, one pair of opposite sides is parallel, while the other pair is not. The trapezoid can have varying angles and side lengths, but this defining characteristic sets it apart from other quadrilaterals.
A trapezium. It has one set of parallel sides. It has four sides.
A quadrilateral with only one set of perpendicular sides is typically a right trapezoid or right kite. In a right trapezoid, one pair of opposite sides is parallel, and the non-parallel sides meet at right angles. In a right kite, two pairs of adjacent sides are equal, and one pair of opposite angles is equal, with one set of sides meeting at right angles.
