ERASER
A Journey Through the Land of Geometry
In the land of Geometry lives Dot.
She is very curious, and wants to know everything.
Hello, Dot.
Hello. Who are you?
I am Pencil.
Oh! Look, Pencil - what an interesting line!
It's so even!
Do you know what it's called?
That is a straight line.
I had no idea that there was such a line,
"straight".
There is a lot that you don't know yet, Dot.
After all, you live in one place all the time.
You should go on a journey!
Then you will see a lot, and learn a lot.
Ha! A journey! I'll go on a journey!
But how can I go alone?
I could get lost.
I guess...
I will go with you.
Are we going to walk much longer?
Will the straight line end soon?
A straight line has no end.
What if we go the other way?
The other way has no end, either.
A straight line has no endpoints at all.
So what, do we have to keep walking on, and on, and on...
without end?
Well, if you don't want to walk endlessly,
let's call for some help from...
scissors.
Hurrah!
Now there's an endpoint at last.
Good job, scissors!
Now, please also make an endpoint on the other side.
Oh, how interesting!
An endpoint on one side,
and an endpoint on the other.
What is this called?
This is a line segment.
You, Dot, are now standing on a straight-line segment.
A straight-line segment...
A straight-line segment!
I'll remember that name.
Scissors, my dears,
please cut some more line segments.
The Eraser rubbed it out again!
Don't cry.
Don't cry, Dot.
Don't be sad.
I'll draw you many different line segments.
Short ones, and long ones.
As for that scoundrel, we'll teach her a lesson yet!
What do we do?
Let's build a bridge.
But how?
See those islands in the puddle?
Yes...
We'll get some help from...
...these line segments.
Hurrah! There's a bridge!
Oh, what an interesting line it turned out to be!
Pencil, what is it called?
It's not straight at all.
This is a broken line.
A broken up line!
Who broke it up?
Not "broken up", just "broken".
You should listen more attentively.
Why won't you let us go any further?
Our city only allows entry to those
who have already learned something about the land of Geometry.
Let me in, then!
I know a lot about Geometry.
Do you know what a triangle is?
No, I don't.
Would you like to know?
Of course I would!
Then look.
What is this?
Hey, that's a broken line!
Correct.
And how many line segments does it have?
Three.
And how many corners, or "angles"?
One, two, three.
Three angles, too!
That is a tri-angle.
Here are its sides,
And here are its vertices.
Are you triangular yourself?
Of course!
All the residents of our city are triangular,
and it is called Triangle City.
Will you now let us into Triangle City?
I will.
Enter.
Ah, Pencil!
Look at how interesting this place is!
There are so many triangles all around!
And they're all so different!
Oh!
Catch that scoundrel!
No longer will you rub things out when nobody's asked you to!
Well, Dot, tell me:
what do you know about the land of Geometry?
Mm... the straight line,
line segments,
the broken line,
and the triangle!
Attaboy, Dot!
Ha-ha, hurrah!
Now I know everything about the land of Geometry!
Don't be silly, Dot!
The land of Geometry is very big,
and we have walked only through the first part of it.
But we're going to keep walking, right?
Of course we will!
