What type of polygon is shown?

convex heptagon
concave heptagon
concave hexagon
convex hexagon

D. Convex hexagon.

Step by step explanation:

We have been given a polygon and we are asked to find type of our given polygon.

Let us count sides of our polygon. We can see that our polygon has six sides. So our polygon is a hexagon.

Now let us see that our hexagon is concave or convex. We can see that our hexagon has no angles pointing inwards and none of its internal angle is greater than 180 degrees.

Therefore, our polygon is a convex hexagon and option D is the correct choice.
