Answer:
Linear pairs are ∠BAC and ∠CAD, ∠BAE and ∠EAD and ∠EAD and ∠DAC.
Step-by-step explanation:
The linear pairs are pair of adjacent angles formed by intersection of two lines and sum up to form an angle of 180°. Linear pair angles are supplementary to each other.
As referred in figure 1, linear pairs are:
∠BAC + ∠CAD = 180° ( ∠BAC and ∠CAD are adjacent to each other and lies on straight line BAD.
In the same way, ∠CAD + ∠DAE = 180° ( sum of linear pair)
∠BAE + ∠EAD = 180° ( sum of linear pair)
