Difference between a diamond and a rhombus?

Answer 1

:( Sorry this answer's soooooo long:

A rhombus, contrary to what some people say, is not identical to a diamond when it is tipped on its side. A rhombus will actually have (when tipped on its side) the top angle slightly behind the bottom angle: aka they are not then same thing.

A diamond is not a mathematical shape. 'Diamond' is from decks of cards, 'Rhombus' is from Math.

BTW, a rhombus is a parallelogram* with opposite acute** and obtuse*** angles and all four sides are the same length.

*opposite sides of the shape are parallel

**less than 90

***more than 90 degrees

A diamond is a very hard, precious stone made of carbon atoms (in a tetrahedral formation) and is a three dimensional object; a rhombus is a two dimensional mathematical shape with all sides equal and opposite angles equal; a rhombus with all angles 90o is called a square.

As a two dimensional shape, a diamond is the name of the shape of one of the suits in a deck of cards and it is a rhombus.
