Geometrical shapes are all around us. They make up the form and structure of every two-dimensional (2D) and three-dimensional (3D) object. In mathematics—namely geometry—and in real life, geometric shapes are two or three-dimensional figures that can be recognized and categorized based on a specific outline/boundary and other attributes including curves, lines, and angles.
2D Shapes. In geometry, a shape or a figure that has a length and a breadth is a 2D shape. In other words, a plane object that has only length and breadth is 2 dimensional. Straight or curved lines make up the sides of this shape. Also, these figures can have any number of sides. In general, plane figures made of lines are known as polygons.
The prior difference between the 2D and 3D shapes is that in 2D shapes only two axis are incorporated x and y-axis. On the other hand, in 3D shapes, the three axis x, y and z-axis are covered. Square, circle, triangle, rectangle are the various 2D shapes while cube, sphere, cuboid, are the 3D shapes. The plan in engineering drawing, which ...
History of 3D Shapes. All 3D shapes have three measurements: length, width, and height. Shapes look different from different directions. All 2D shapes are only measured by their length and width. Aristotle said that 2D shapes are lines and not figures or bodies. They are always described as extensions of lines or areas bounded by lines.
A shape is 2D if it is flat. 2D means it has two dimensions: length and breadth. or. length and height. 2D shapes include circle, triangle, square, rectangle. pentagon, hexagon.
These shapes only occupy an area. These shapes occupy both area and volume because they have a depth/ height. Type of View. The 2D shapes give us a simple view of any object. The 3D shapes give us an architectural view of any object. Visibility of Edges. Every edge is very clearly visible in the case of 2D shapes.

Nov 24, 2023 · A 2D shape has two dimensions, that is, Length and Breadth. A 3D shape has three dimensions, that is, Length, Breadth and Height or Depth. 2D shapes are used to give simple view of an object. 3D shapes are used to give architectural view of an object. A 2D figure is plotted on two axes, that is, the X- and Y-axes.
