I have made many crib blankets - that is what I called them - they are the blankets that my kids, grandkids, nieces and nephews have drug around!! My mom and I have made a ton of them - my standard size is 45 x 48 inches - it fits in the crib - and it is big enough to lay on a floor for to play on and tuck around a car seat in the car.
not every parallelogram is a rhombus though any parallelogram with perpendicular diagonals the second property is a rhombus in general any quadrilateral with perpendicular diagonals one of which is a line of symmetry is a kite
The Rhombus. A rhombus is a four-sided shape where all sides have equal length. Also opposite sides are parallel and opposite angles are equal. Another interesting thing is that the diagonals (dashed lines in second figure) meet in the middle at a right angle. In other words they bisect (cut in half) each other at right angles. A rhombus is sometimes called a rhomb or a diamond.
