[school bell rings]

A stick figure teacher stands in a classroom next to an old TV set and a chalkboard that reads "Shapes" and shows a triangle, a square and a rectangle.

He says OKAY, SETTLE DOWN, CLASS.
LET'S LOOK AT
SOME TRIANGLES.
CAN ANYONE TELL ME HOW
MANY SIDES A TRIANGLE HAS?

[coughs]

The teacher says NOBODY?
OKAY, A BIG HINT'S ON
THE BOARD BEHIND ME.
IT HAS THREE
INTERSECTING POINTS.
ANYONE?
REALLY?
YOU'RE MAKING THIS A LOT
HARDER THAN IT NEEDS TO BE.
OKAY, LET'S JUST
WATCH THE VIDEO THEN.

[cheers]

He turns on the old TV.

(music plays)

As several triangles appear on screen, a song plays that says
TRIANGLES HAVE THREE SIDES -
ONE, TWO, THREE
THOSE SIDES CAN BE DIFFERENT
ARE YOU LISTENING TO ME?
LET'S GET MORE SPECIFIC
I HOPE THAT YOU ARE KEEN
THERE'S equilateral, isosceles and scalene.
IF A TRIANGLE HAS
THREE EQUAL SIDES
ALL LENGTHS THE SAME
WE GIVE THAT TRIANGLE
A SPECIAL NAME
IF YOU GUESS IT IT
WOULD BE SO ADMIRABLE
THAT TRIANGLE IS
An equilateral.
IF A TRIANGLE HAS TWO
SIDES THAT ARE EQUAL
AND ONE THAT IS NOT
A SPECIAL NAME THIS
TRIANGLE HAS ALSO GOT
IF YOU KNOW THE ANSWER,
PLEASE TELL ME
THIS TRIANGLE IS AN
Isosceles.
NOW IF A TRIANGLE HAS SIDES
AND NONE ARE THE SAME
WE ALSO GIVE THIS TRIANGLE
A VERY SPECIAL NAME
PLEASE TELL ME
WHAT YOU KNOW
DON'T BE MEAN
THIS TRIANGLE IS A
Scalene.

The song ends and the stick figure teacher turns off the old TV.

He says THE LENGTH OF THE SIDES
ON A TRIANGLE TELL YOU
THE STORY BEHIND WHAT
KIND OF TRIANGLE IT IS.
I GUESS YOU CAN SAY THERE ARE
THREE SIDES TO EVERY TRIANGLE.

[rim shot]

The teacher says OR, I'LL HAVE A TRIANGLE
WITH ONE SIDE OF FRIES,
ONE SIDE OF SALAD, AND ONE
SIDE OF BREAD, PLEASE.
[laughing]
I MUST BE HUNGRY.
WHEN'S LUNCH AROUND HERE?
