For instance, The cube has all the square-shaped sides. Some 3D shapes have their base and top parts or cross sections such as 2D shapes. They have a depth so they take a certain amount of volume. The most important terms with the geometric shapes of 3D are faces, edges, and vertices. Similarly, we have many 3D shapes all around us like a table, chair, notebook, pen, etc.ģD shapes are solid objects or objects with three dimensions (length, width, and height), compared to objects with only two sides in length and width. A football is an example of the sphere which is a three-dimensional figure while a circle drawn on a piece of paper is a two- dimensional figure. 3D shapes can also be defined as the solid shapes having three dimensions length, width, and height. The shapes that occupy space are called 3D shapes. 2D Figures have at least three 2D straight sides and they are known as polygons and that includes triangles, squares, and quadrilaterals. Except for the circle which is a curved figure, all 2-D shapes have sides, corners, and internal angles. Circles, squares, rectangles, and triangles are some examples of two-dimensional objects and these shapes can be drawn on paper. A polygon is a 2-Dimensional shape composed of vertical line segments connected to one another, thus giving it a closed shape. They are not thick and can only be measured in two dimensions. In geometry, 2D shapes can be defined as completely flat plane figures and only two dimensions - length and width. But, every 2D shape is flat and is enclosed. As each shape has a different number of sides and for each shape, properties vary. There are no fixed properties of the 2D shape. Also, these figures can have any number of sides. Straight or curved lines make up the sides of this shape. In other words, a plane object that has only length and breadth is a 2 dimensional shape. In geometry, a shape or a figure that has two dimensions namely a length and a breadth is called a 2D shape. Examples of three-dimensional shapes are sphere, cylinders, cones, etc. Plane geometry or two-dimensional geometry deal with the flat figures that can be drawn on a piece of paper like line, curves, polygons, quadrilaterals, etc, while solid geometry or three-dimensional geometry deals with solid shapes or three-dimensional shapes. It does not occupy any space called 2d shapes, but if we keep a real notebook on that piece of paper it occupies some space, and such shapes are called 3d shapes or three-dimensional shapes. What we observe is a plain picture drawn on paper. Let us draw a picture of a notebook on a piece of paper. It is broadly classified into two types: plane geometry called 2d shapes and solid geometry called 3d shapes.
