Vertical Angles

This is a picture of floor tiles. Their angles create vertical angles and they are all congruent because they are formed by the same lines at the same angles. For example, 1 and 3 are vertical angles and 4 and 2 are vertical angles. This object was found in my kitchen, but tiles can be found in many places. In the real world tiles are used as a from of flooring, wall coverings, or counter coverings. They can be found outside and inside. In the real world carpenters use them and any person who walks on them uses them. I took this picture.
