How is a square different from a rhombus?

Answer 1

For a square, both of the diagonals equal each other, but on a rhombus the diagonals can equal each other, but it's possible for them to not equal each other. The angles are equal on a square (90 degrees). On a Rhombus, opposite angles are equal but adjacent angles need not be equal.

In a rhombus, the sides don't have to be perpendicular to each other. In a square, all angles are 90 degrees.

A square is a rhombus, but a rhombus is not a square. A square has all 90 degree angles.

The sizes of the angles do not have to equal 90° as in a rhombus, they do in a square.

A rhombus has 4 equal sides. A square has 4 equal sides and also 4 equal angles that are right angles. A square is a special case of a rhombus

Answer 2

A rhombus is a tetragon (or quadrilateral, what ever you want to call it) has two sets of parallel lines, all which are the same length.

A square fits the above description, therefore, a square is a rhombus. For a two dimentional object to be square, it must fit the descriptions for the rhombus as well as have 4 right angles.

Answer 3

A square is a rhombus whose angles are all 90 degrees.
