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
Yes, a rhombus is a quadrilateral with four equal sides. Drawing a diagonal divides it into two triangles, which are clearly congruent by SSS. So we get that corresponding angles of the triangles are congruent. If we then consider the diagonal to be a transversal, this implies that opposite sides are parallel.
