N'ihi ya, azịza ya bụ akụkụ anọ nwere akụkụ abụọ ma ọ dịkarịa ala otu n'akụkụ abụọ. <eng> The relevant information is: 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.
So, the final answer is a convex quadrilateral with at least one pair of parallel sides.
