We can think of space in terms of dimensions. For example, A 2-dimensional space is called a plane. A 3-dimensional space is, well, a 3-dimensional space! What's a 1-dimensional space called? How about a 0-dimensional space? The intersection of two distinct 2-dimensional spaces is a space of how many dimensions? The intersection of two distinct 1-dimensional spaces is a space of how many dimensions? Explain your answers. Extend this idea to 3-dimensions and beyond.
