Quadrilaterals Overview

A quadrilateral in which at least one pair of sides are parallel and consecutive angles from different bases are supplementary.

A trapezoid in which opposite sides are parallel.

A quadrilateral in which four sides can be grouped into two distinct pairs of congruent sides that are adjacent to each other, one pair of angles are congruent, and diagonals are perpendicular.
