Question

In the given figure, lines $AB$ and $CD$ intersect at point $O$.​(iii) Name all the pairs of adjacent angle.

Answer 1

Given , Line $AB$ and $CD$ interesect at a point $O$.

Now we know that, two angles are said to be adjacent angles if .

• They have their vertices at the same point.
• They have one common arm.
• The other arms of the angles are on the opposite sides of the common arm.

Adjacent angles are:

$\angle BOD$ and $angleBOC$

$\angle AOC$ and $angleBOC$

$\angle DOA$ and $angleAOC$

$\angle AOD$ and $angleBOD$

Hence, above are the required adjacent angles.
