And now it's time for Angles of a Polygon, a shmoop production.

00:13

Hello, everyone.

00:15

Welcome to Geometry Tonight. I'm Mary Hart. This evening, we're going to take a closer

00:18

look at one of our biggest stars. . .

00:19

. . .Polly Gon. The rumor is that she's been keeping a

00:23

secret. . .

00:23

. . . and she's about to let us in on it. Polly, great to see you. What's the scoop?

00:31

<<Polly>> Oh, it's nothing really. It's just my angles.

00:35

<<Mary>> Your ankles? Well, they are lovely. <<Polly, a little testy>> Not my ankles, you

00:40

twit, my angles.

00:42

As you know, I'm famous for being a many-sided individual. . .

00:45

. . .and I want to let my fans know how easy it is to determine all my angles no matter

00:51

what shape I'm in. <<Mary>> Oookkkaaay.

00:54

<<Polly>> It's quite simple really. All you have to do is divide me into triangles.

00:59

Since all triangles have 180°, you just have to add them up to know my angles.

01:05

<<Mary>> Well, that's very interesting...

01:08

... but what about when you, how can I say this, balloon up a bit?

01:12

<<Polly angrily>> THAT was for a part -- the female remake of Raging Bull.

01:17

<<Mary>> Sorry. You were saying. <<Polly>> No matter what size I am, I can

01:22

still be divided into triangles. <<Mary>> Oh, I get it. I think I'm seeing

01:27

a bit of a pattern here. <<Polly>> Well, I should hope so.

01:30

If you count my sides and subtract 2, you get . . .

01:33

<<Mary interrupting>> . . . the total number of triangles!

01:35

<<Polly>> I think this interview is finished. <<Mary>> There you have it. Once again Geometry

01:42

Tonight scoops the world. . .

01:43

. . .join us tomorrow when we find out what circles Ray Dius is travelling in . . .

01:48

. . . until then, happy calculating and may all your angles be right.
