A quadrilateral with four equal sides but no right angles is a rhombus.
A square. Four 90 degree angles allow a quadrilateral to have equal sides.
A square has four sides so it is a quadrilateral. All sides of a square are of equal length so it is equilateral. All angles of a square are of equal measure so it is equiangular. A quadrilateral that is equilateral and equiangular is a regular quadrilateral.

A rhombus
The four angles of a quadrilateral add up to 360 degrees.
A rhombus is not a pentagon, it's a quadrilateral.
A Rhombus has four equal sides but not (necessarily) four equal angles.
A square or a rectangle... though technically they have four equal angles...
A square.
A quadrilateral with four equal sides but no right angles is a rhombus.
A square. Four 90 degree angles allow a quadrilateral to have equal sides.
It is no different from a quadrilateral.A quadrilateral is any shape with four sides and a rhombus has four sides, therefore it is a quadrilateral.
(1) Parallelogram A parallelogram is a quadrilateral with two sets of parallel sides. The opposite or facing sides of a parallelogram are of equal length, and the opposite angles of a parallelogram are equal.(2) SquareA square is a regular quadrilateral. This means that is has four equal sides and four equal angles.(3) RhombusA rhombus is a quadrilateral whose four sides all have the same length. Opposite angles of a rhombus have equal measure. The two diagonals of a rhombus are perpendicular.(4) RectangleA rectangle normally refers to a quadrilateral with four right angles.ParallelogramSquareRhombus
