Polygon ABCDE has 5 sides. Which is a correct description of the polygon? A. It is a concave pentagon because segment AE would extend into the inside of the polygon, and it has five sides. B. It is a convex hexagon because it has six sides and none of the sides would extend into the inside of the polygon. C. It is a concave hexagon because segment AE would extend into the inside of the polygon, and it has six sides. D. It is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.

Step 1:
Let's solve this step by step:

Step 2:
: Understand the definition of a polygon

- A polygon is a closed plane figure with straight sides - The number of sides determines the polygon's name - A pentagon has 5 sides - A hexagon has 6 sides

Step 3:
: Analyze the number of sides

- The problem states the polygon has 5 sides - This means it is a pentagon, not a hexagon

Step 4:
: Understand concave vs. convex polygons

- A convex polygon has no interior angles greater than 180° - In a convex polygon, all vertices point outward - If any line segment between two vertices extends inside the polygon, it is concave

Step 5:
: Examine the description of segment AE

- The problem states segment AE would extend into the inside of the polygon - This means the polygon is concave, not convex

Step 6:
: Combine the information

- 5 sides = pentagon - Segment AE extends inside = concave

Final Answer

It is a concave pentagon because segment AE would extend into the inside of the polygon, and it has five sides.
