# 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\epsilon \iota \delta \stackrel{\xb4}{\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 (http://planetmath.org/Equilateral) nor right-angled (http://planetmath.org/RightAngle).”

Below is a picture of a rhomboid.

The for the area of a rhomboid is the same as that for all parallelograms: If $b$ is the length of its and $h$ is the length of its , then $A=bh$.
