Answer:
Convex Polygon: A polygon is convex if all its interior angles are less than 180 degrees and no vertices point inward. This means that for any two points inside the polygon, the line segment connecting them will also lie entirely inside the polygon.
Non-Convex (Concave) Polygon: A polygon is non-convex, or concave, if it has at least one interior angle greater than 180 degrees. In such a polygon, at least one vertex "points inward," meaning that a line segment between some points within the polygon can pass outside of it.
