2D shapes, or two-dimensional shapes, are shapes that have only two dimensions, length and width, and are flat. Here are a few examples:
Square: A square is a 2D shape with four equal sides and four right angles.
Rectangle: A rectangle is a 2D shape with four sides and four right angles, but unlike a square, its opposite sides are equal in length.
Circle: A circle is a 2D shape with all points equidistant from a fixed center point.
Triangle: A triangle is a 2D shape with three sides and three angles. There are different types of triangles, such as equilateral, isosceles, and scalene.
Pentagon: A pentagon is a 2D shape with five sides. If all its sides and angles are equal, it's known as a regular pentagon.
Hexagon: A hexagon is a 2D shape with six sides. If all its sides and angles are equal, it's known as a regular hexagon.
And there are many more. Two-dimensional shapes are a fundamental concept in geometry and are used extensively in various fields such as mathematics, physics, engineering, and computer graphics.

Today I am going to visit the magical world of shapes. I want you to learn all about 2D shapes
and their properties. But what is a 2D shape? 2D shapes are what we call flat shapes that are
completely flat like drawing on a sheet of paper. Let's go and see if we can meet some of these
shapes. Here we are in shape world. Isn't it beautiful? Now let me tell you some important
shape words before we find some shapes. We use the word side to describe the number of
lines needed to make a shape. We use the word corner or vertex to describe the point where two sides
meet. Sides can be straight as you see on this square or sides can be curved as you see on this
Lots of shapes can be symmetrical. A shape is symmetrical when it is the same on both sides.
A shape has symmetry if a central dividing line or a mirror line can be drawn on it
to show that both sides of the shape are exactly the same. Now let's meet the shapes.
Ah Suzy Square's house. Let's see if she's at home. Hello, how are you? Hello Suzy, I am very well.
Would you mind if I asked you a few questions? Not at all. Suzy, can you tell us what is special
about you? Well, I have four straight sides and four corners. What is very special about me
is that all my sides are equal in length. They are all the same length. Also, I am symmetrical.
This means that I have four lines of symmetry. As you can see, square shapes are everywhere.
Windows, books and chess boards. Thank you Suzy, that is very interesting. She lives next door.
Ah, that's Sissy Circle. Actually, she is in her garden. Bop over, she would like to see you.
Hello Sissy Circle, how are you today? Oh, hello Aaron. Would you like a taste of one of my
delicious and perfectly round blueberries? Yes please, yummy. Sissy, I have a question for you.
What makes your shape so special? Well, Aaron, you are right. Circles are very special.
As you can see, I don't have any corners. I only have one long curved side, which means I am very
good at rolling. Also, I am very symmetrical. I have an infinite number of lines of symmetry.
My favourite circle shapes are wheels and cars or bikes, clocks and this beautiful sun in the sky.
Thank you Sissy. Do you know where Timmy Triangle lives? Of course, Aaron. He lives just down the
street. Number 16. Thank you for the delicious blueberries. I will see you soon. Number 16.
Let's go and meet Timmy Triangle, another interesting shape. Hello Timmy Triangle,
what are you doing? Oh, hello Aaron. I am just eating my lovely triangular sandwich.
Would you like one? Yes please. All this learning about shapes has made me very hungry. Do you mind
if I ask you all about triangles? What's special about triangles? Oh, we are very, very special
indeed. We are the only shape that has three straight sides and three corners. We can be
symmetrical, but it depends on what type of triangle you are. You can see us in lots of
places. Slices of pizza, street signs and of course yummy sandwiches.
They really are yummy. Well, I have to continue on my journey. Does Ricky Rectangle still live near
the lake? Oh yes. Tell her I said hello. Hello Ricky Rectangle, how are you today?
What are you reading? Oh, I see. A Rectangular. All about rectangles. Very interesting.
Hi Aaron. Yes, it is very interesting. Did you know that rectangles are very special shapes?
Yes, I did. But what makes you so special? Well, we have four straight sides and four corners.
We are different from squares because we have two short sides and two longer sides.
We are symmetrical too and we have two lines of symmetry. We do look a bit like a square.
Yes, we do. But don't forget our sides are not equal. That's what makes us different.
Rectangles are very popular. You can find them everywhere. Books, mobile phone, computer screens,
football pitches, car windows. Oh, I could go on all day. You certainly could but I will let you
go back to reading your book. I have to see Perry Pentagon. He lives just over the bridge.
Good seeing you Aaron. Enjoy the rest of your day. Hi Perry Pentagon. How are you today?
What are you doing? You look a bit hot. Oh, I was in my football skills. Want to play?
I would love to later but I've got a question for you first. What makes pentagons so special?
Well, I have five straight sides and five corners. We're also symmetrical. Can you guess how many
lines of symmetry we have? Well, you have five sides and five corners so that means you have
five lines of symmetry too. You are very clever Aaron. Can you see the pentagons on my football?
They're my favorite type of pentagons. Wow, yes I can see them. Thank you Perry Pentagon.
I have to rush on as I want to see Harry Hexagon before I have to go home. Okay Aaron,
lovely to see you. Until Harry, I will see him later at football practice.
I certainly will. Now, if I remember Harry Hexagon's house is just around this corner.
Ah yes, here is and there is Harry Hexagon. And what is he doing? Harry, why are you running
around your garden like that? Oh, hello Aaron. A bee was chasing me. Well, you should never annoy
bees Harry Hexagon. I wasn't annoying him, he was annoying me. How are you Aaron? Well,
I'm good. I called to ask you a question about hexagons. Yes, of course. What would you like
to know? I can tell you all about hexagons. They have six straight sides and six corners.
We are very symmetrical as we have six lines of symmetry. What else would you like to know?
Whoa, that was just what I was about to ask. Oh, that was an easy question. Some points are
a hexagon shape. Oh, and of course the honeycomb in a bee's hive. Oh, maybe that bee thought I
was trying to steal his honey. Yes, of course. That's why he was chasing me. Well, I better get
home before the bee comes back. I hope you enjoyed learning with us. Can you spot any 2D shapes?
Let's recap on what you've learned today about 2D shapes. A 2D shape is what we call a flat
shape. We use the term sides to describe how many lines are used to make a shape.
We use the term vertex or corner to describe the point where two sides meet.
Sides can be straight or curved. Here are some useful words to help you think about 2D shapes.
Side, vertex, corner, straight and curved. I really hope you enjoyed exploring shape world with us.
Can you remember how many sides the pentagon has?
