Question

Can two adjacent angles be complementary ? Draw figure​

Answer 1

Answer:

Two adjacent angles can be complimentary, if they add up to 90∘, i.e. the sum of two angles formed should be 90∘. ... From the figure ∠ABD and ∠CBD are adjacent angles from the same vertex. They are also complementary as the sum of the angles is 90∘, i.e. ∠ABD+∠CBD=30∘+60∘=90∘.
