in Shot on 2b, 4. the above sheet again to it so an of 45° can be as in, 4. Fold the above sheet again to make it double so that an angle of 45° can be made as shown in, figure., 45, .06-, 5. Now take another coloured pastel sheet and draw a circle of same radius and cut it and fold it, along its diameter to make a semicircle., 6. Now tri-fold the semicircle as shown in the figure. The obtained angle is of 60°., 7. Now unfold this angle once to make an angle of 120°., 120°, Observation, Through paper folding we can make protractor to measure the angles., Result, Using papers students will be able to make the angles of 30°, 45°, 60°, 90°, 120° and 180°., a semici, Learning outcome, Through the above activity students are able to make their own protractor by using paper cutting, folding., Activity time, 1. Make your own protractor by making angles of 30°, 45°, 60°, 90° and 120° and verify it ur, real protractor., 35
