Explain the following terms draw figures also:
i) Linear Pair
ii) Adjacent Angles
iii) Parallel Lines
iv) Supplementary Angles
Answers
Answer:
Let us draw the diagram showing two straight lines AB and CD intersecting each other at point O.
(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.
