Name a two dimensional shape that results from combining and splitting?
"Compare and describe two dimensional shapes that result from combining and splitting common shapes"
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.
Compare and Describe 2D Shapes
Combining Shapes: The process of joining two or more shapes together to create a new shape. Splitting Shapes: The process of separating a shape into two or more shapes. Two-dimensional shapes: Shapes that have length and width but no depth, such as circles, squares, triangles, and rectangles.
