Trapesium
a trapezium
An impossible figure
There are actually I think two with only two parallel sides. A square and a rectangle
Trapezium.
The Rectangle and the Parallelogram both have 2 pairs of parallel sides. The Trapezium has 4 sides but only 2 are a parallel pair. The Kite has 2 pairs of equal sides but none parallel. The limits is an irregular quadrilateral with no side equal or parallel to another.
A trapazoid has only has to have 1 set parallel sides a parallelogram is 2 sets of parallel sides
Only one quadrilateral has only two parallel sides: the trapezium.
I think it is a trapizoid
a parallelogram is a quadrilateral with four parallel sides. a trapezoid is a quadrilateral with two parallel sides.
Squares, rectangles, parallelograms and rhombuses have 2 pairs of parallel sides. The trapezoid has only 1 pair of parallel sides.
It is a quadrilateral with exactly 2 pairs of parallel sides.
