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 concave polygon has at least one interior angle greater than \(180^\circ\) (or a "dent" in the shape). The given polygon has a vertex where the interior angle is greater than \(180^\circ\), so it is concave.

Answer:

concave
