A square and a rhombus are 4 sided quadrilaterals that have congruent sides
a square
A rhombus.
4 sides
A square, but not a rhombus because a rhombus does not have four congruent angles

RectangleA rectangle has 4 congruent angles, but two pairs of congruent sides instead of all sides being congruent.
An ireggular square has sides all the same lenght but all the angles are not congruent
A rhombus is a quadrilateral whose four sides are congruent. Squares are a type of rhombus with congruent angles. Since there are 4 contruent angles, they must all be right angles.So any quadrilateral that is equilateral is a rhombus and any rhombus with 4 right angles is a square. Every rhombus is a parallelogram because the opposite angles of a rhombus are congruent. Also, the diagonals of a rhombus are perpendicular.
