A transversal is a line that crosses two or more lines. When the lines crossed by a transversal are parallel, we can figure out the values of all the angles formed with just one given angle.In the same way that alternating squares on a chess board are the same color, alternating angles are equal.

To do this, we like to imagine the set of lines as a chess board so that the colors can help us identify which angles are equal.

### angles equal to the given angle

### angles equal to the supplementary angle of the given $(180_{∘}−given angle)$
