A concave polygon looks sort of like a vertex has been 'pushed in' towards the inside of the polygon.
A convex polygon has all the vertices of the polygon pointing outwards, away from the interior of the shape. Think of it as a 'bulging' polygon.
A regular polygon is a polygon which is equiangular (all angles are congruent) and equilateral (all sides have the same length). Regular polygons may be convex or star.
