What is a trapizoid and how many sides?

A trapezoid, also known as a trapezium in some regions, is a four-sided polygon (quadrilateral) with at least one pair of parallel sides. The parallel sides are referred to as the bases, while the other two sides are called the legs. Trapezoids can be classified into different types, such as isosceles trapezoids, where the legs are of equal length. Overall, a trapezoid has four sides.
