00:00

Triangles, a la Shmoop. Goldilocks has had it up to here with bears.

00:09

Understandably so. She is also through with porridge...

00:12

... ever since she tried the delicious, crispy, cheesy crunch of a Shmorito Nacho Cheese flavored

00:18

chip.

00:18

Well she's on a Corn Chip bender now.

00:21

Seriously, she needs help. She can't stop herself from raiding the homes

00:27

of poor, innocent families in search of their cheesy chips.

00:31

One day she picked the wrong cottage... She tore into one of the bags... but was disappointed

00:36

with the first Shmorito she grabbed.

00:39

Goldi is very picky about her Shmorito shapes, and this one was clearly an obtuse triangle...

00:44

...which had one angle that was greater than 90 degrees.

00:46

She tried talking some sense into it, but it didn't seem to understand.

00:48

The next Shmorito had the opposite problem -- all of its angles were less than 90 degrees.

00:52

It's a shame, because the Dorito was pretty acute, but Goldi was compelled to keep looking.

00:58

Many of the Shmoritos in the bag were equilateral triangles.

01:01

All of their sides were congruent, but it still wasn't doing it for Goldi.

01:06

"Too perfect," she thought. She also came across a Shmorito that was Isosceles,

01:14

with two equal sides.

01:15

"Not perfect enough," Goldi thought. There was a scalene Shmorito...

01:21

...with three sides of completely different lengths.

01:23

"Must have been an accident at the Shmorito factory," Goldi thought.

01:31

Just when she was about to give up...

01:32

...Goldi finally happened upon a Shmorito with a right angle.

01:36

"A right triangle!" Goldi shouted excitedly. "Ah... now this one is juuuuust right."

01:46

Unfortunately, Goldi's pickiness cost her in the end.

01:50

In all the excitement, she hadn't heard the deer come home.

01:52

These deer loved their Shmoritos as well.

01:55

Goldi was about to wish she had tangled with a family of bears.
