Which statements are true about polygons? Select three options. Students, if you believe you earned partial credit on this problem, please reach out to your teacher. All sides and all angles in a polygon are congruent. The sides of a polygon are segments that intersect exactly two other segments, one at each endpoint. In a polygon, all segments with a common endpoint are collinear.
