Theorems

Diagonals of Rhombi are perpendicular. If the Diagonals of a parallelogram are

perpendicular, then the parallelogram is a Rhombi.

Example:

If BD AC, then Square ABCD is a Rhombus.

Similarities

Squares and Rhombi are convex quadrilaterals.

Both pairs of opposite sides are parallel. Rhombi and squares have all the

properties of a parallelogram. A square has all the properties of a

rhombus.

Similarities Cont.

All sides of a rhombi and square are congruent.

Diagonals are perpendicular in a square and a rhombi.

Diagonals bisect the angles of the rhombi and square.

Each diagonal of each shape bisects a pair of opposite angels.

Differences

A square has all right angles. A rhombus doesn’t have to have right

angles. If a rhombus has right angles it can be

considered a square. On a square both diagonals equal each

other.
