Take a ruled sheet of paper. Draw (in thick colour) two parallel lines l and m. Draw a transversal t to the lines l and m. Place a tracing paper over the figure drawn. Trace the lines l, m and t. Slide the tracing paper along t, until l coincides with m. You find that angle '1' on the traced figure coincides with angle '2' of the original figure. Observe and see if there are any other angles that are coinciding
