Question

what kind of polygon is this? convex concave

Explanation:

To determine if a polygon is convex or concave, we check the interior angles. A convex polygon has all interior angles less than \(180^\circ\) and all vertices pointing outward. A concave polygon has at least one interior angle greater than \(180^\circ\) (a "dent" or a vertex pointing inward). The given polygon has one vertex that points inward (creating a "dent"), so it has an interior angle greater than \(180^\circ\), making it concave.

Answer:

concave
