What is the difference between rhombus and a square?

A rhombus is a quadrilateral containing 2 pairs of parallel sides. All sides are the same length and opposite angles are equal as well.

A square is a special case of a rhombus, where the angles are all 90 degrees.

Every square is a rhombus, but not every rhombus is a square.

A rhombus is a parallelogram. Remember that opposite sides of a parallelogram are always congruent. A rhombus also has two pairs of opposite congruent angles. Angles that are across from each other are congruent.

A square is a type of rectangle. Remember, a square is a type of quadrilateral that has all sides equal. A square has diagonal lengths that are equal but a rhombus does not. Lastly, each of the angles of a square measure 90 degrees but opposite angles are equal for a rhombus.    

hi,

you half the rectangle that you ae asking about so then you would see the scale factor of 1/2 the one u have selected, the one on top is half.

hope this !
