'2D' stands for 2-dimensional. A 2D shape is any shape that has two dimensions. Think about what it means to have two dimensions for a moment. If we had only one dimension to work with, we could only move backwards or forwards in a line. A line is one-dimensional. If we had two dimensions, on the other hand, we could go forwards and backwards in a line and turn in any direction to start a new line. We are essentially able to travel anywhere on a flat surface. In mathematics, a flat surface is called a plane. A plane is one example of a two-dimensional shape. A plane is essentially the largest sheet of paper you will ever find. In fact, it is a sheet of paper so large that it never ends. One way of thinking about 2D shapes is anything that lays flat on a piece of paper.
2D shapes lay flat on a piece of paper.
Take out a piece of paper, and place it on your desk. Notice how flat it is. Now take any nearby object, place it on your piece of paper, and trace around it. Look at your shape. What does it look like? Congratulations, you have just drawn a 2D shape! This is another way you can think of 2D shapes: 2D shapes are any shape you can trace from an object on a flat piece of paper.
Take a cube and trace it on a piece of paper and you will get a square shape. Take a soda can and trace it on a piece of paper. Depending on how you lay the soda can down, you will get either a circle or a rectangle. Try it out and see for yourself.
