Question

From the following figure, find the adjacent angles.

• A. $\angle$FOE and $\angle$BOC
• B. $\angle$FOA and $\angle$EOD
• C. $\angle$AOB and $\angle$BOC
• D. $\angle$FOE and $\angle$DOC

Answer 1

The correct option is C $\angle$AOB and $\angle$BOC

Two angles are said to be adjacent angles, if they have:
a common vertex,
a common arm and
the non common arms must be on the opposite side of the common arm.

This is satisfied only by the pairs of angles $\angle$AOB and $\angle$BOC.
Hence $\angle$AOB and $\angle$BOC form adjacent angles.
