Shai Gar's Math Challenge 4

[Shai Gar]

When does a pentagon have 4 sides?

 

[xrevolutionx]

It always has 4 sides.

 

[Shai Gar]

that's a rectangle.

the correct answer is "When it intersects a plane".

 

[xrevolutionx]

Not necessarily. An object can not have 5 sides exclusively. There must be 4 in order for there to be a 5th.

 

[Shai Gar]

it's a september 11 joke.

 

[xrevolutionx]

oohhh. Can't say I like it. I'm in the U.S. Army.

 

[Shai Gar]

Hey, it's just Friendly Terrorism.

You know... Like Friendly Fire.

 

[xrevolutionx]

I get ya. It did strike a nerve though. Gotta watch out for those kinds of posts. That day still resonates with a lot of people here.

why is it always math? why can it be something easier?

 

[NaeturVindur]

but...but...but... when a pentagon intersects a plane, its a line segment, not an explosion!

 

[xrevolutionx]

If you want to get real technical, when a two dimensional object intersects another plane, it becomes 3 dimensional. So a pentagon would end up having more than 5 sides, not 4.

 

[NaeturVindur]

huh? We have a pentagon, a plane, and... what? Also, when three planes intersect, you get a point. If they're spread out enough to describe a 3D object, then they aren't all intersecting.
