Answer:
sometimes
Explanation:
If the polygon is regular that is the length of each side of the polygon is equal and each angle is equal in that case only interior angles are equal .
For a polygon even if a side length is different or interior angle is different then its a irregular polygon and then in that case each interior angle cannot be termed as equal.
Thus, we know that that there are two type of polygon regular and irregular.
Thus, it can be said that it is not necessary that Each of the interior angles in a polygon are equal always
Also it can be said that it is not necessary that Each of the interior angles in a polygon are never equal (as regular polygon have equal angles)
Thus, we can only say that each of the interior angles in a polygon are sometimes equal .
