Objective: Introduce different types of lines and their properties
Subtopics to be covered:
- Difference between line and line segment
- Types of lines -> intersecting, parallel, perpendicular, transversal
- Angles made by a transversal on parallel lines
Learning Outcome:
- Students can identify type of line or angle from a given set
- Students can solve problems to find measure of angles in a given figure

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
