Construction in the classroom

Don't discard a ruler that has broken! A broken ruler can still be used to draw a line segment of a given length. Swati Sircar, from Shikshamitra, shows us how. She also shows us how to draw an angle with a given measure.

Note: This presentation relies heavily on animation. To view it properly, please download the ppt file and view it using powerpoint (as a slideshow).
