Aim By paper cutting and pasting verify that angles in the same segment of a circle are equal.
coloured paper, a pair of scissors, geometry box, fevistick, carbon paper.
step 1 Draw a circle of any radius with centre O on a coloured paper and cut it.
step 2 Take a rectangular sheet of paper and paste the circle cut out on it.
step 3 Fold the circle in anyway to get a chord. Name the chord as AB.
step 4 Take two points P and Q in the same segment.
step 5 Form a crease joining AP and draw AP.
step 6 Form a crease joining BP and draw BP.
step 7 Form a crease joining AQ and draw AQ.
step 8 Form a crease joining BQ and draw BQ.
step 9 Make replicas of angle AQB and angle APB using carbon paper.
step 10 Place the two replicas on each other.
1. angle APB and angle AQB are angles in the same segment of the circle.
2. angle APB = angle AQB.
angle APB = angle AQB
ANGLES IN THE SAME SEGMENT OF A CIRCLE ARE EQUAL.
- Mathematics teacher since 1994. After joining teaching profession I realized two things. First one- there is so much which is still to be learned and the second one - there is no standard method for teaching .Each day a new challenge randomly comes forward . For overcoming, there is a need to explore, learn and change. I believe learning is not confined to the four walls of the classroom.Enormous tools are available on the web which may be utilised for making teaching/learning interesting and effective.For me teaching is not just a job,its a passion,a commitment...a mission.
