The woman in this image is using a crosswalk to go from one side of a street to another—she's crossing the street. In the language of geometry, the crosswalk is known as a transversal line. The word transverse comes from a Latin word that means "to lie across something." The crosswalk is a line or pathway that lies across the lines formed by the street.
When a transversal crosses two or more lines that lie in the same plane, it automatically forms several angles. In the diagram below, notice eight angles are formed when the transversal t intersects with lines a and b.
Question
What kinds of angles are formed by the transversal of the crosswalk lying across the broken lines in the street?
Right angles are formed.
