Q:

How many sides does a trapezium have?

A:

A trapezium is a quadrilateral that consists of four sides that are not parallel. If one pair of these sides were parallel, it would be called a trapezoid. If both pairs were parallel, it would be a parallelogram.

The area of a trapezium is calculated by dividing it into two triangles. The sum of the areas of those two triangles is the area of the trapezium. The perimeter of a trapezium is calculated by adding the lengths of its four sides. In Britain, the meaning of trapezium and trapezoid are reversed compared to the American definition. The etymology of trapezium dates back to the Late Latin word with the same spelling that meant "little table."

A parallelogram is a two-dimensional rhomboid or quadrilateral with four sides. The four sides, or edges, consist of two pairs, each with the opposite side parallel and congruent. The two pairs of consecutive angles, or vertices, in a parallelogram are supplementary, which means that the sum of the angles in each consecutive pair is 180 degrees.

A kite is a quadrilateral, a shape with four straight, flat sides, that has two pairs of sides where the two adjacent sides, the ones that meet, are equal in length. The two angles in a kite where the sides with different measurements meet are identical. The other two angles may or may not be identical.
