Answer:
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
U graph it like if it was just number don't pay attention to the verbal
