Type of Polygon: Dodecagon Convex or Concave: Concave Regular or Irregular: Irregular
Practice makes perfect
This polygon has 12 sides, so it is called a dodecagon. Let's draw the lines containing the sides to check whether they have points in the interior of the polygon.
Since the red dashed lines have points in the interior of the polygon, we know that our polygon is concave. Because the polygon is not convex, it must be irregular.
