As performed in real lab:
Colored papers, a pair of scissors, gum, compass, pencil, ruler, carbon paper or tracing paper.
- Draw circle of any radius and cut it using scissor.
- Take a rectangular sheet of paper and paste circle on it.
- Take two points A and B on circle and draw AO and BO, O is centre of circle.
- Take another point P on remaining part of the circle and draw AP and BP using ruler and pencil.
- Make two replicas of ∠APB and paste these replicas adjacent to each other on ∠AOB.
As performed in the simulator:
- Mark a point on the workbench area such that it forms radius for the circle with point O as the origin and length of the radius must be in between 2 to 5 cm.
- Mark any two points (A, B) on circle such that considerable distance is maintained between two points.
- Mark point P in remaining part of the circle to form ∠APB.
- Click on ∠APB to create replica.
- Click on both colored angles to rotate.
- Place both replica adjacent to each other on centre O .
- The student will observe that two replicas of ∠APB completely covers ∠AOB.
