This picture reminds me of measuring. Like when construction workers have to measure out stuff so it will fit in that certain place. Measuring stuff for that reason is really important. If nobody would have thought of measuring, just about every single building would collapse or something. Also, measuring is important for games like basketball. There wouldn't be an exact 3-point line or anything. Like with football, they yard lines would be off by either a little bit or a lot and would be uneven.
