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 (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 $A=bh$ .
