Answer :
Answer:
B). ∠BAC and ∠CAD
C). ∠BAE and ∠EAD
D). ∠EAD and ∠DAC
Step-by-step explanation:
As we know, a linear pair consisting of angles at a single point of the line has a sum of 180° in total. In other words, two supplementary angles together comprise a linear pair. In the given figure, the pair of supplementary angles ∠BAC and ∠CAD, ∠BAE and ∠EAD, and ∠EAD and ∠DAC are the linear pairs as their sum is 180°. Thus, options B, C, and D are the correct answers.
