1. Circles Model - Angles in same segment of a circle Circles Model - Angles in same segment of a circle JUHI MATHUR -2011

2. Concept- In any Circle, angles in the same or equal segments are equal. Concept- In any Circle, angles in the same or equal segments are equal.

3. Step -1 Draw a circle

4. Step-2 Draw another circle with same radius. Mark chord AB on the circle and measure it. Make any angle AEB subtended by chord AB in the major segment.

5. Step-3 Draw another circle with same radius. Mark chord AB (same measure) on the circle and measure it. Make any angle ADB subtended by chord AB in the major segment.

6. Step-4 Draw another circle of same radius. Mark chord AB (same measure) on the circle and measure it. Make any angle ACB subtended by chord AB in the major segment.

7. Step-5 Cut out Triangles ACB, ADB and AEB A B D A B C A B E

8. Step-6 Place the three Triangles ACB, ADB and AEB cut out previously on the circle drawn in Step-1

9. What do you observe when you place Angle ACB, ADB and AEB one over other with vertices A and B coinciding respectively for all angles?
