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
A rhombus is a quadrilateral with opposite sides parallel and all sides equal length. A rhombus whose angles are all right angles is called a square. A rhombus (or diamond) is a parallelogram with all 4 sides equal length. * Units: Note that units of length are shown for convenience. They do not affect the calculations. The units are in place to give an indication of the order of the calculated results such as ft, ft 2 or ft 3. Any other base unit can be substituted.
