Fun Geometry Question: If given the following 5-sided polygon with area A units squared, can you find a 3-sided polygon having the same area by messing with the given polygon?

OpenStudy (zarkon):

do I give away the answer...or just wait for someone else to figure it out :)

myininaya (myininaya):

If you want someone else to discover it, then I guess we wait.

myininaya (myininaya):

I had to play a little with it, but it looks like we can do the same process for any convex n-gon to any convex (n-k)-gon.

OpenStudy (zarkon):

sure...by induction...this being the basis step (or one vertex more than the basis step)

OpenStudy (zarkon):

Hopefully a student will drop in and try it. :)

OpenStudy (amistre64):

im kinda wondering what "messing with the given polygon" might be defined as. I tried yelling at it, but not too sure if that worked :)

myininaya (myininaya):

Well what was the reaction?

OpenStudy (amistre64):

it recoiled in horror and confessed to being a three sided equi-areal assessment. I then gave it a cookie and we watched NCIS together, but on mute.

myininaya (myininaya):

Yep, it wasn't suppose to react that way to that kinda messing.

OpenStudy (amistre64):

kids these days, they just cant be trusted lol

myininaya (myininaya):

Is the polygon a kid, now?

OpenStudy (amistre64):

it might as well be .... if it sits there and argues with you and spews lies at every given moment, then it has to be a kid that spends all day sitting on the couch eating the chicken potpies straight out of the freezer.

OpenStudy (amistre64):

did i mention, my daughter is living with me now? ;)

myininaya (myininaya):

So you have a polygon living with you?

myininaya (myininaya):

Just remember you cannot enter into a polygon. There is no opening. You can not hop into it.

OpenStudy (amistre64):

a 3 sided polygon that is disguising itself as a 5 sided poly of indeterminable area. We are in flatland right?

myininaya (myininaya):

Yes.

OpenStudy (amistre64):

all these polys look the same to me :)

ganeshie8 (ganeshie8):

straight lines

ganeshie8 (ganeshie8):

guess i found a method, il wait for others to try proly

OpenStudy (amistre64):

my method is patent pending .. so no stealing it!!

myininaya (myininaya):

What kinda straight lines are you talking about exactly?

ganeshie8 (ganeshie8):

was saying in amistre's flatland its all straight lines he sees.. he may not even see polys :) solution looks too simple after letting it settle in my head a bit... its just to do with making few constructions to straighten up multiple sides.
