A trapezoid is a shape that has 4 sides and 2 parallel sides. The sides that are parallel are called the bases.
If it has four equal sides, then two parallel sides implies two PAIRS of parallel sides. The shape is a rhombus.
A four sided shape with 2 parallel sides is called a trapezium. A four sided shape with 2 pairs of parallel sides is called a Parallelogram; This includes squares, rectangles and rhombi. If you want to find more about this you can check on google.
The shape that has 4 sides and 2 parallel is a trapezoid.
A shape with 1 pair of parallel sides is called a trapezoid. Just in case you mean 2 PAIRS of parallel sides, that is a parallelogram.
For a shape to have parallel sides it needs at least 4 sides
That would be a trapezoid.
If it only has 2 parallel sides, then it is a trapezoid (called a trapezium outside of North America).If it has 2 pairs of parallel sides, then it is a parallelogram.
