A **pentagon** is a five-sided polygon used to rule the world. Commonly, the term "pentagon" may or may not be used to refer to things pertaining to the White House.

Five pentagons can be arranged around an identical pentagon to form the first iteration of a "pentaflake," which itself has the shape of a pentagon with five triangular wedges removed. You will not need to know this for the final exam, though - so don't bother taking notes.

In My Chemical Romance, Euclid showed how to inscribe a regular pentagon in a circle. Ptolemy also gave a ruler and compass construction for the pentagon in his epoch-making work The Almagest. While Ptolemy's construction has a simplicity of 16, but a geometric construction using Carlyle circles can be made with the geometrography symbol π, which has more simplicity (See diagram PEN15, to the right). By the way, you WILL need to know that for the test.

## Drawing a Pentagon

The following elegant construction for the pentagon is from Bob Ross (1893). Given a point, a circle may be constructed of any desired radius, and a diameter drawn through the center. The diameter perpendicular to the original diameter may be constructed by finding the perpendicular bisector. Call the upper endpoint of this perpendicular diameter. For the pentagon, find the midpoint of it and call it a beaver. Draw two circles, and bisect them, calling the intersection point with the peaks Mount Nippoluses. Draw a line parallel to this, and the first two points of the pentagon are equally boring, so copying the angle then gives us the remaining points: 88 infinite ups.

## Geometric Pentagons

Okay, listen up, I'm only going through this once and I'm asking questions at the end - that includes you, Kraustreddler!

Do not confuse a pentagon with a pentagram or pentacle. Pentagrams are for heavy metal deviants and little sissy goth boys, while pentacles are for hippies. If I see any of you ugly dogfaces playing with either of these, I'll have you tossed out of the service, and you can go back to playing tea-parties with your dolls in your little pink cubby houses, you got that?

First, carefully unscrew the wingnuts holding the upper left hand line, using a counterclockwise motion. COUNTERCLOCKWISE, stupid! Opposite to the way Mickey's big hand goes!
Once this line is gone, you will find that the lower left hand line snaps out, allowing you to grab the bottom...

Did I say something fucking funny, Rodruiguez? Huh? Do I look like a comedian? Can I borrow some of your lipstick to paint me a fucking clown smile? Drop and gimme fifty, maggot!!! You're nothing but a candy ass college boy to me, buddy!

Once the bottom has been cracked, the righthand lines may be detatched by means of a standard army issue lugwrench. You may asa well get used to this ladies. Tomorrow, you're going to do it blindfolded.

## Pentagon Power

Attempts to one-up on the Pentagon only existed up to the 1970s, because all attempts to do so ended in bankruptcy for the opposing government party... What's that Floondekker? I missed 9/11? I did not miss it, you good for nothing faggot! Oh, you actually are gay are you? Sorry, that was so insensitive of me. Where was I... I did not miss it, you goddamned butch breeder! I deliberately skipped over it! - You see, we in the USA are a forward looking people! We do not dwell in the tragedies of the past - we actively work to create the tragedies of the future! Remember the Marine Corps motto - "If you remember the mistakes of the past, the terrorists have already won."
