RECTANGLES
Copy on the Rectangles Flap.
Properties
1. All properties of the
parallelogram.
2. The diagonals are .
3. Four Right Angles
Rectangles
Theorems (Ways to Prove)
1. If the diagonals are ,
then it’s a rectangle.
2. If it has 4 right angles,
then it’s a rectangle.
RHOMBUS
Properties
1. All properties of a
parallelogram.
2. All sides are equal.
3. Diagonals are ┴.
4. Diagonal bisect
opposite angles.
Rhombus
Theorems (Ways to Prove)
1. If it has 4  sides, then
it is a Rhombus.
2. If the diagonals are ┴,
then it is a Rhombus.
3. If the diagonal bisects
each pair of opposite
angles, then it is a
Rhombus.

Parallelogram, a
Rectangle, and a
Rhombus
Ways to Prove:
1. If it is a rectangle and
a rhombus, then it is a
