Identify a pair of vertical angles in the figure

1) ∠ADB and ∠EDC

2)∠ADE and ∠BDC

Step-by-step explanation:

Definition of vertical angles: Each of the pairs of opposite angles made by two intersecting lines are known as vertical angles.

So, in the given figure there are two intersecting lines named as AC and EB

So, the pair of vertical angles are :

1) ∠ADB and ∠EDC

2)∠ADE and ∠BDC

Thus these are the pairs of vertical angles in the given figure .

Hence  a pair of vertical angles in the figure are :

1) ∠ADB and ∠EDC

2)∠ADE and ∠BDC
