Answer:
Explanation:
A trapezoid is a quadrilateral with at least one pair of parallel sides. In other words, a trapezoid has two opposite sides that are parallel, called the bases, and the other two sides are called the legs or lateral sides.
So, to conclude that a quadrilateral is a trapezoid, you must determine that:
1)Two of its sides are parallel.
2)The other two sides are not parallel.
If these two conditions are met, then the quadrilateral is a trapezoid.
(If a trapezoid has two pairs of parallel sides, then it is known as a parallelogram, which is a special type of trapezoid.)
