Looking at the polygon in the image, I can count the sides to answer your question:

1. Counting the sides: The polygon has 6 sides.

2. Convex or Concave: The polygon is concave. This is because at least one of its interior angles is greater than 180°, as indicated by the inward indentation on the top left side.

3. Name of the polygon: Since it has 6 sides, the polygon is a hexagon.

Would you like more details on any of these concepts?

Here are some relative questions to consider:

1. What is the difference between a concave and a convex polygon?
2. How do we classify polygons with more than 6 sides?
3. What are the characteristics of a regular hexagon compared to an irregular one?
4. Can a concave polygon ever be regular, and why or why not?
5. How do the interior and exterior angles differ between convex and concave polygons?

Tip: A quick way to check if a polygon is concave is to see if you can draw any line through the shape that crosses its boundary more than twice.
