# Practice problems of the trapezoid

Trapezoid is a convex quadrilateral with one pair of parallel sides but referred to as a trapezium 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.#### Number of problems found: 269
