It becomes a square when its every angle is a right angle. A quadrilateral that has two pairs of consecutive congruent sides, but opposite sides are not congruent. Advertisement Remove all ads. Tip: To visualize this one, take two pens or pencils of different lengths and make them cross each other at right angles and at their midpoints. (The two diagonals of a parallelogram bisect each other.) A rhombus is a parallelogram whose diagonals are perpendicular to each other. Syllabus. A rhombus is a proper subset of a square. A square is a 4 sided figure whose diagonals bisect each other at right angles. If the diagonals of a quadrilateral are perpendicular bisectors of each other, then it’s a rhombus (converse of a property). Rhombus 2. Concept Notes & Videos 273. Parallelogram.
