Question

1. describe the shape below.

a 7 - sided (heptagon) concave polygon.
a 6 - sided (hexagon) convex polygon.
a 5 - sided (pentagon) simple polygon.

Explanation:

1. First, count the number of sides of the polygon: By carefully looking at the shape, we can see that it has 7 sides.
2. Then, determine if it's concave or convex: A concave polygon has at least one interior angle greater than 180 degrees (or has "indentations"). This shape has indentations, so it's concave.
3. Analyze the other options: The second option says 6 - sided and convex, but we counted 7 sides and it's not convex. The third option says 5 - sided, which is incorrect as we have 7 sides. So the correct description is a 7 - sided (heptagon) concave polygon.

Answer:

A. A 7 - sided (heptagon) concave polygon.
