[Author - Kripa S]


1. Share examples of point, line segments from daily life. (example: star, bat, tubelight, side of a fan, bench, door etc)

2. Make 8-10 chits of different types of angles. Hand over one chit to one bench and ask them to enact what angle they are. Eg: If it is an acute angle, the students will stand close to middle student, if it is an obtuse angle, the students will stand far away from the middle student. If it is right angle, the students will stand on his one side and in front to depict 90 deg.

3. 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. (TB: page 107 activity)
