Which of the following polygons is classified as a non-convex polygon?

Which of the following polygons is classified as a non-convex polygon?

Step 1: Understand what a polygon is. A polygon is a shape with straight sides, like a triangle or a square.
Step 2: Learn about convex and non-convex polygons. A convex polygon has all its angles less than 180 degrees, and all points on the shape are outward.
Step 3: Identify what a non-convex polygon is. A non-convex polygon has at least one angle greater than 180 degrees, and it can have points that point inward.
Step 4: Recognize examples of non-convex polygons. A star-shaped polygon is a common example because it has points that extend inward.
Step 5: Conclude that the star-shaped polygon is classified as a non-convex polygon.
