Dear Student,
b) In case of a concave polygon a diagonal may lie in exterior.
c) The sum of angles of a Quadrilateral is 360°
Convex polygon : A polygon for which both diagonals entirely inside the polygon. All interior angles are less than 180°
Concave polygon : A polygon for which one of the diagonal is not entirely inside the polygon. One or more interior angles more than 180°
Regards
