In Euclidean geometry, a convex quadrilateral with at least one pair of parallel sides is referred to as a trapezium () in English outside North America, but as a trapezoid () in American and Canadian English. 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 parallelogram with four equal sides; an oblique-angled equilateral parallelogram

a quadrilateral all of whose sides have the same length.

In plane Euclidean geometry, a rhombus (plural rhombi or rhombuses) is a quadrilateral whose four sides all have the same length. Another name is equilateral quadrilateral, since equilateral means that all of its sides are equal in length.
