MCQ
What is the maximum exterior angle possible for a regular polygon$?$
- A$60^\circ$
- B$80^\circ$
- ✓$120^\circ$
- D$160^\circ$
Since of increasing size of regular polygon $\Rightarrow $ its exterior angle decreases.
$\therefore$ Mass exterior angle is for a regular triangle (equilateral triangle) and $= 180 -$ interior angle
$= 180^\circ - 60^\circ = 120^\circ $
