Have you ever wondered what shape has 5 sides? You may have heard of triangles and squares, but did you know that there are many other shapes with different numbers of sides? These shapes are called polygons, and they are fascinating objects that can be found all around us in the world of math and geometry.

So, what exactly is a polygon? A polygon is a two-dimensional shape that is made up of straight lines and has no curves. In other words, it is a flat shape that is composed of line segments. A polygon can have any number of sides, as long as each side is straight and they connect to form a closed shape.

Now, let’s talk about the shape that has 5 sides. This shape is called a pentagon. The word “pentagon” comes from the Greek words “penta” meaning “five” and “gonia” meaning “angle”. As the name suggests, a pentagon has five angles and five sides.

There are different types of pentagons, depending on the length of their sides and the measure of their angles. For example, a regular pentagon has all sides and angles equal, while an irregular pentagon has sides and angles that are not all equal. A convex pentagon has all of its interior angles less than 180 degrees, while a concave pentagon has at least one angle greater than 180 degrees.

Pentagons can be found in many different places in the world around us. For example, the United States Department of Defense headquarters building, known as the Pentagon, is a five-sided polygon. Many stars in nature also have a pentagonal shape, such as star-shaped flowers or certain types of crystals.

In conclusion, polygons are fascinating shapes that come in many different varieties. If you were wondering what shape has 5 sides, the answer is the pentagon! We hope you enjoyed learning about this interesting shape and the many ways it can be found in the world around us.

Remember, learning about shapes and geometry can be fun and exciting. Keep exploring the world of math and you never know what amazing discoveries you might make!
