A square
a rhombus or a square
This is called a Parallelogram. Each pair of opposite sides will then be the same length. If all four sides are the same length, and opposite sides are parallel, then it is a rhombus. NB: If all four sides are the same length then the opposite sides must be parallel.
rhombus
triunghiul echilateral
They are the pairs of sides which are parallel.
NO!!!! Parallelogram has two pairs of opposite sides which are parallel. These pairs of opposite sides are the same length. Trapezium ; has one pair of opposite sides which are parallel. These parallel sides are NOT the same length .
NO!!!! Parallelogram : Two pairs of parallel lines ; The each pair of parallel lines is the same length. Trapezium ; One pair of parallel lines, that are not the same length. The other two sides can be the same length , but not parallel. Both figures/shapes are quadrilaterals.
The difference between a trapezoid and a parallelogram is very simple: A trapezoid has exactly one pair of parallel sides and a parallelogram has exactly two pairs of parallel sides.
A Rhombus had 2 pairs of parallel sides and has NO right angles. :)

A four-sided figure with two pairs of parallel sides the same length and four right angles is called a square.
