Definición

• Rounded Corners.  The shape of a rectangular plaquette or plate with two or four corners trimmed with a curve instead of square corners; each round corner is an arc one-fourth of a circle. The shape is symbolic of portability; it is easier to carry than an item with square corners (as if it prevented dog-eared corners from being carried about). If all four corners are rounded the shape is called pillow shaped.
