This is a trapezoid (or trapezum, depending on what country you live in).
The only requirement for a trapezoid is that one pair of opposite sides be parallel. There could be trapezoids with a pair of perpendicular lines.
A right trapezoid has exactly one pair of perpendicular lines and is a quadrilateral.
a hexagon
The question contradicts itself. A dodecagon need not have any perpendicular sides.
If both pairs of opposite sides are parallel: A Rectangle, or a Square. If exactly one pair of opposite sides are parallel: An Isosceles Trapezoid. If it does not have parallel sides and one diagonal is the perpendicular bisector of the other: A Kite It is also possible that it does not have any parallel sides and neither diagonal is the perpendicular bisector of the other: A quadrilateral
The only requirement for a trapezoid is that one pair of opposite sides be parallel. There could be trapezoids with a pair of perpendicular lines.
trapezium
A quadrilateral that has only one pair of parallel sides (the other pair not parallel) is a trapezium.
A trapezoid is defined as a four-sided figure (quadrilateral) with at least one pair of parallel sides. The other pair of sides can be either parallel or non-parallel, and they are not necessarily perpendicular. In some cases, a trapezoid may have perpendicular sides, but this is not a requirement for its classification.
No, a parallellogram is a quadrilateral with two pair of congruent sides and a trapezoid is a quadrilateral with only one pair of congruent sides.
There is no quadrilateral on that list that has only 1 pair of parallel sides.
A right trapezoid has exactly one pair of perpendicular lines and is a quadrilateral.
Yes, a trapezoid is a quadrilateral with only one pair of parallel sides.
A quadrilateral with only one pair of parallel sides is a trapezoid.
