Rhombus Properties Activity1. Give each student a rhombus (or have students
draw their own using a straightedge)2. Trace rhombus with labels and diagonals on a
quarter piece of patty paper.3. Place brad through the diagonal intersection.4. Rotate Rhombus ABCD 180° so it maps onto
itself.
What do we notice??

What other properties do Rhombi have?
Using another rhombus, measure and .Then, measure and
The diagonals of a rhombus the angles.
Measure the angles created by the intersection of the diagonals.
The diagonals of a rhombus are to each other.

Rectangle vs. Parallelogram vs. RhombusWhat do we notice about the properties of a rectangle and of a parallelogram when it is rotated onto itself?
They have the same properties!
Do rectangles have the same properties as
rhombi?
No, because rhombi have to have 4 congruent
sides.
