In this lecture broadly explain on What are Trapezoids. It is a tutorial study based presentation. Trapezoids are quadrilateral with exactly one pair of parallel sides. The inclusive definition sets up a relationship between parallelograms and trapezoids that is exactly analogous to to the relationship between squares and rectangles. Here also briefly focus on Isosceles Trapezoid Properties: Base Angles Are Congruent and Diagonals Are Congruent.
