While i understand the rationale given for why a circle is not a polygon. In the video (PrepSwift > Geometry > Polygons and Vocabulary) you have mentioned towards the end that if you add infinite sides to a polygon it becomes a circle so a circle is a perfect polygon which leads to a discrepancy in the quiz.
