# rhomboid

A *rhomboid* is a parallelogram that is neither a rhombus nor a rectangle. The word rhomboid comes from the Greek word $\rho o\mu\beta o\varepsilon\iota\delta\acute{\eta}\varsigma$, which is transliterated as ‘rhomboeidis’. In *The Elements*, Euclid has this definition:

“Of quadrilateral figures….a rhomboid (is) that which has its opposite sides and angles equal to each other but is neither equilateral nor right-angled.”

Below is a picture of a rhomboid.
