Welcome to the world of polygons! Today, we’re going to explore these cool geometric shapes that you can find all around you. Have you ever noticed the shapes of signs or kites? Let’s dive into my sketchbook and learn more about them!
Polygons are special shapes that are made by connecting straight lines to form a closed figure. Imagine drawing a shape without lifting your pencil, and when you finish, you end up where you started. That’s a polygon!
Let’s look at some examples:
Polygons have different parts:
Polygons can be regular or irregular:
We can also name polygons based on the number of sides they have:
And there are more! A seven-sided polygon is called a heptagon, and an eight-sided one is an octagon. You can learn the names by using the right prefixes.
Here’s what we’ve learned about polygons:
Polygons are everywhere! Just look around, and you’ll start noticing them in everyday objects.
Did you enjoy learning about polygons? Keep exploring, and you’ll find even more amazing shapes!
Polygon Hunt: Go on a polygon hunt around your home or classroom! Look for objects that have polygon shapes. Can you find a triangle, quadrilateral, or hexagon? Draw or take pictures of the objects you find and label the type of polygon each one is. Share your findings with your classmates and see who found the most different types of polygons!
Create Your Own Polygon: Use craft sticks or straws and some clay or playdough to create your own polygons. Try making a triangle, a square, and a pentagon. Count the sides and vertices of each shape. Can you make a regular polygon where all sides and angles are the same? What about an irregular one?
Polygon Story Time: Imagine you are a polygon living in a world of shapes. Write a short story about your adventures. What kind of polygon are you? Do you meet other polygons? What do you do together? Share your story with your friends or family and see if they can guess which polygon you are!
Sure! Here’s a sanitized version of the transcript:

Welcome to Smile and Learn! Today, we’re going to talk about polygons—those geometric shapes found everywhere. Can you see that sign over there? Look at that kite! I’m going to draw them in my sketchbook.

Wow! All these objects are polygons. A polygon is a plane figure described by a closed polygonal line. Look at these shapes. Can you see a polygon?
The first shape is not a polygon because its polygonal line is not closed. The second shape is not a polygon either because it has a curved side. The third shape is a polygon because it’s formed by a closed polygonal line.
Polygons are formed in several parts:
– The sides are each of the lines or segments that form the polygon.
– The vertices are the points where all sides meet.
– The angles are the spaces determined between two adjacent sides.
– The diagonals are the segments that connect two non-adjacent vertices.
We can classify polygons in different ways: regular or irregular, and depending on the number of their sides. A regular polygon has all sides and angles equal, while an irregular polygon does not have all angles or all sides equal.
Here you can see some examples of regular and irregular polygons. Polygons can also be classified depending on the number of their sides:
– Triangles are polygons that have three sides. This slice of pizza has a triangular shape.
– Quadrilaterals have four sides. This sandwich or this kite are quadrilaterals.
– Pentagons have five sides. This swimming pool has the shape of a pentagon.
– Hexagons have six sides. These honeycomb cells have the shape of a hexagon.
There are many types of polygons, but to learn how to read them, you need to use the corresponding prefix. It’s very easy! A seven-sided polygon is a heptagon, and an eight-sided polygon is an octagon, and so on.
Let’s recap everything we learned about polygons:
– They are plane figures described by a closed polygonal line.
– They are formed by parts: sides, vertices, angles, and diagonals.
– They can be classified as regular or irregular, and also depending on the number of their sides.
Like math, polygons are everywhere! You only need to look around you and pay close attention.
