  2. PROCEDURE

  3. DRAW A CIRCLE OF ANY RADIUS ON THE CHART SHEET 2. MARK CHORD AB OF MEASURED LENGTH ON THE CIRCLE. 3. MAKE ANOTHER CHORD CD OF SAME MEASUREMENT ON THE CIRCLE

  4. 4. JOIN THE CHORDS AB AND CD WITH CENTER O 5. YOU WILL GET TWO TRIANGLES OAB AND OCD 6. COLOUR THE TWO TRIANGLES IN TWO DIFFERENT COLOURS

  5. 7. USING TRACING PAPER , TRACE TRIANGLE OCD AND COLOUR IT IN SAME COLOUR AS TRIANGLE OCD 8. CUT THE TRACED TRIANGLE NEATLY • PLACE THE TRACED TRIANGLE OCD • ON TRIANGLE OAB AND MATCH ANGLE AOB AND ANGLE COD . WHAT DO YOU OBSERVE?

  6. Record and Report your Observations as Under OBSERVATIONS Radius of Circle = ________ CM Length of AB= ___________ CM Length of CD = ___________CM Angle AOB= Angle _______ Angle COD= Angle_______

  7. THANKYOU
