Question

Draw two lines AB and CD such that they intersect at point 'O'.
Trace the figure given below on a tracing paper. Place the traced figure
over the figure given below and rotate it such that ZDOB coincides ZCOA
Do This
Observe the angles ZAOD and ZBOC also ZCOA and ZDOB.
You will notice that ZAOD= ZBOC and ZCOA= ZDOB.
B
3
D
We can conclude that vertically opposite angles are equal.
Note: Take two straws. Fix them at a point O’with a pin. Place them such that the straw on top
covers the one below.Rotate the straws. You will find that they make vertically opposite angles,​
