is a square a rhombus? Yes, because a square is just a rhombus where the angles are all right angles. It is more common to call this shape a rhombus, but some people. the main difference between a square and a rhombus is that all the angles of a square are equal to 90°, whereas, the angles of a rhombus are not equal to 90°. It is often said that a square is a rhombus, but a rhombus isn’t always a square because a square fulfills all. The little squares in each corner mean right angle. A square has equal sides (marked s) and every angle is a right angle (90°) also opposite sides are parallel.
