This free parallel lines and transversals coloring page can be enlarged into a poster for a math word wall or can be given to each student to put into their notebooks. Parallel lines cut by a transveral can be a tricky topic for some Geometry students. Through the activity of coloring the angles, students will start to make connections between the positioning of the angle pairs and their relationships.
