Naming 2D shapes
Do you know the names of all the 2D shapes? Can you describe them using mathematical language?
2D shapes
2D (two-dimensional) shapes are flat, while 3D (three-dimensional) shapes are solid objects with length, breadth, and depth. Read on to learn about 2D shapes. What are 2D shapes? Definition 2D stands for 2-dimensional. 2-dimensional shapes are flat and only have two dimensions: length and width. They include squares, rectangles, circles, triangles, and more. What are 2D shapes? If a shape has two dimensions, it means there are 2 ways it can be measured in space. All 2D shapes can be measured by their length and width or length and height. But remember, shapes that are 2D are completely flat. For example, the square below is a shape in 2D because it's flat and has straight sides. |
