## Flashcard Content Overview

This flashcard set covers basic two dimensional (2D) and three dimensional (3D) shapes. 2D shapes are those that can lie on a flat surface, or plane in the mathematical sense. They only have two dimensions, which means they can only travel in two directions, such as forwards and backwards. 3D shapes occupy three dimensions. This means they take up air and space. In this sense, traveling can occur forwards, backwards, right, left, up and down. The ability to travel up into space and back down is what differentiates 3D from 2D. The world we live in is all 3D.

Shapes are all around us. Every day we encounter different 2D and 3D shapes. This flashcard set covers some of the most basic shapes such as: square, triangle, circle, sphere and cube. You probably know most of these and see them on a daily basis. However, did you know there are other shapes like: decagon, septagon, triangular prism and octahedron? If some of these terms are new to you, don't fret. Studying this flashcard set will help you with distinguishing 2D shapes from 3D shapes. You will also be able to identify many common 2D and 3D shapes, as well as others that are not seen everyday.
