skew lines

This picture represents skew lines. Skew lines are similar to parallel lines in the way that they don't ever touch. They are different in the way that their slope is not the same, so they are going in different directions. This is a picture of a street sign. It is made from metal so it relates to the metal fabrication industry. Many poeple use this in the real world to find their way. It can be used so that people dont get lost and know where they are going.
