Answer
A four-sided figure with exactly one pair of parallel sides is called a trapezoid.
Work Step by Step
A trapezoid is a special type of Quadrilateral with four sides that has exactly one pair of parallel sides.All the angles of a trapezoid are of different degree measure.A trapezoid is further classified according to the measure of the degree of an angle. For example, if in the trapezoid the angles formed by the base sides are equal in the measure is called isosceles trapezoid.
If a trapezoid is forming two right angles, then it is called right trapezoid.
