Step-by-step explanation:
Step 1 :

The statement in option 3 and 4 is not represented by the Venn diagram as it is not the definition of a triangle
Angles are complementary when they add up to 90 degrees. For example 60 and 30, or 45 and 45.
Angles are supplementary when they add up to 180 degrees. For example 90 and 90, or 100 and 80.
