Question

what kind of polygon is this? image of a trapezoid - like polygon concave convex

Explanation:

To determine if a polygon is convex or concave, we use the definition: A convex polygon has all interior angles less than \(180^\circ\) and all vertices pointing outwards. A concave polygon has at least one interior angle greater than \(180^\circ\) (a "dent" or indentation). The given quadrilateral (a trapezoid - like figure) has all vertices pointing outwards, and no interior angles are greater than \(180^\circ\). So it is a convex polygon.

Answer:

convex
