Try a square or parralellogram.
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.
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 .
I am a rhombus. I don't need to prove that my opposite sides are parallel. If I'm a quadrilateral with four sides that are the same length, then I am definitely a rhombus.
a square
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 quadrilateral
A Paralellogram
a rhombus
They are the pairs of sides which are parallel.
A square fits into the description.
A Rhombus
Yes. By definition, opposite sides are equal (i.e. same length) and parallel.
