Question

what kind of polygon is this? concave convex

Explanation:

To determine if a polygon is concave or convex, we check the interior angles. A concave polygon has at least one interior angle greater than \(180^\circ\) (or a "dent"), while a convex polygon has all interior angles less than \(180^\circ\) and all vertices point outward. Looking at the given polygon, one of its interior angles is greater than \(180^\circ\) (it has a "dent"), so it is a concave polygon.

Answer:

concave
