 
 <translate> In Euclidean geometry, a convex quadrilateral with at least one pair of parallel sides is referred to as a trapezoid (/ ˈtræpəzɔɪd /) in American and Canadian English but as a trapezium (/ trəˈpiːziəm /) in English outside North America. The parallel sides are called the bases of the trapezoid and the other two sides are called the legs or the lateral sides (if they are not parallel; otherwise there are two pairs of bases). A scalene trapezoid is a trapezoid with no sides of equal measure, in contrast to the special cases below.

Answer this question: when can a quadrilateral also be called a trapezoid? Let's give stream of consciousness first: <hau> A cikin lissafin Euclidean, ana kiran murabba'i mai murabba'i tare da akalla nau'i biyu na bangarori masu layi daya a matsayin trapezoid (/ ˈtræpəzɔɪd /) a cikin Ingilishi na Amurka da Kanada amma a matsayin trapezium (/ trəˈpiːziəm /) a Turanci a wajen Arewacin Amurka. Ana kiran bangarorin da ke layi daya da tushe na trapezoid kuma sauran bangarorin biyu ana kiransu kafafu ko bangarorin gefe (idan ba su da layi daya; in ba haka ba akwai nau'i biyu na tushe). Scalene trapezoid shine trapezoid ba tare da bangarorin daidai ba, sabanin yanayin musamman da ke ƙasa.  Amsa wannan tambaya: yaushe za a iya kiran quadrilateral kuma trapezoid? Bari mu ba da rafi na sani na farko:
