trapezial
Like a trapezoid
Trapezial is an adjective relating to a trapezium—a four-sided figure with one pair of parallel sides in British usage, or no parallel sides in American usage.
In anatomy, trapezial describes structures associated with the trapezium bone, a small carpal bone at the base of the thumb: trapezial arthritis causes pain during gripping.
The word appears primarily in medical and geometric contexts.
