Angle $\angle ABC$ marked in the figure is
a) acute angle        (b) obtuse angle         (c) reflex angle       (d) none of these

"

Given :

Angle $\angle ABC$ is given in the figure.

To find :

We have to find the type of the given angle $\angle ABC$.

Solution :

Acute angle -  $\displaystyle 0\ < \ \theta \ < \ 90° $ 

Obtuse angle - $\displaystyle 90° \ < \ \theta \ < \ 180° $

Reflex angle - $\displaystyle 180° \ < \ \theta \ < \ 360° $

The given angle $\angle ABC$ is more than 180° and less than 360°.

Therefore,   $\angle ABC$ is Reflex angle.
