In Euclidean plane geometry, a quadrilateral is a polygon with four edges (or sides) and four vertices or corners. Sometimes, the term quadrangle is used, by analogy with triangle, and sometimes tetragon for consistency with pentagon (5-sided), hexagon (6-sided) and so on.
Making the world better, one answer at a time. A quadrilateral is any four sided shape. It can be a square, parallelogram, rhombus,; anything with four sides. Congruent means the same, so that would mean the same angles, same size, and the same measurements. Two rhombuses with the same angle measurements, and size, would be congruent.
