Scale Factor, a la Shmoop.

Hey there, and welcome to SCALE FACTOR!
- 00:10
Where we make contestants face their deepest darkest fears…of geometric shapes.[Male contestants preparing to face their fear]
- 00:15
Get that rhombus away from me! Okay, let’s jump right in.
- 00:19
Contestant #1, you’ve got…this triangle…with side lengths of 10, 25 and 35…and your scale [A computer monitor with a triangle and measurements]

factor…is point-four.
- 00:28
GO! Ohhh…too bad, so sad.
- 00:32
Gotta buzz in there a bit faster, contestant.
- 00:34
As I’m sure you all well know, a scale factor tells us the proportion by which we’re either [Definition of scale factor on a chalkboard and a spider on the top left]
- 00:38
reducing or enlarging a shape.
- 00:42
With a scale factor between 0 and 1, as in this case, we’ll be reducing the shape’s size.
- 00:47
A scale factor of point-four means the new shape will be 40% of the original’s size… [Triangle and a 40% smaller triangle]
- 00:52
…meaning your scaled triangle should have had sides of 4, 8 and 14.
- 00:57
Next time, don’t be afraid to hit your buzzer thing a little earlier… [Man shrugging his shoulders]
- 01:00
Okay, Contestant #2! We’re giving you a triangle with side lengths of 6, 8 and 11…
- 01:06
…and a scale factor of 5.
- 01:09
What’s your new shape look like?
- 01:11
OHHHH…that’s a shame. Dilly-dallying cost you there. [Contestant unhappy at not buzzing in]
- 01:14
When we have a scale factor over 1, you simply multiply the dimensions of your shape by that number.
- 01:20
So here, you should have gotten a triangle with sides of 30, 40 and 55.
- 01:26
That’s a big ‘un. Let’s find out if Contestant #3 can take
- 01:30
advantage of his opponents’ sluggishness…
- 01:33
Contestant #3?
- 01:34
Huh. Well, it appears that Contestant #3 has left the building. [Contest #3 walking away from the building]
- 01:38
Some people just cannot face their fears head on.
- 01:41
Which means… we have no winner yet again tonight… 48 days running.
- 01:45
We’ll see if we can keep that record going tomorrow night on…SCALE FACTOR!! [Scale factor show logo]
