Question

Consider the following statements:
When two straight lines interest:
i)adjacent angles are complementary
ii)adjacent angles are supplementary
iii)opposite angles are equal
iv) opposite angles are supplementary

Of these statements
Which of the following are correct​

Answer 1

Step-by-step explanation:

(i) When two lines intersect adjacent angles are complementary.

This statement is incorrect.

As the adjacent angles form a linear pair and they are supplementary.

(ii) When two lines intersect adjacent angles are supplementary.

This statement is correct.

As the adjacent angles form a linear pair and they are supplementary.

(iii) When two lines intersect opposite angles are equal.

This statement is correct.

As the vertically opposite angles are equal.

(iv) When two lines intersect opposite angles are supplementary.

This statement is incorrect.

As the vertically opposite angles are equal.

∴ Statement (ii) and (iii) are correct.
