2D shapes are figures that have two dimensions: length and width. They can be combined and split to form different shapes. Combining two shapes, like squares and circles, can create a new shape like a rectangle. Splitting a shape, like a circle, can create two equal-sized semicircles. When shapes are combined, new edges are created. When shapes are split, existing edges are divided.
