its because they dont fit perfectly in each other, so the rectangle cant really exist, just take the slopes of the hypotenuse on the triangles as the slopes of the long side of the trapezoids, the triangles have a slope of 8/3 (2.33) and the traezoids have a slope of 5/2 (2.5) , it only looks like they line up

you found it on 4chan. but the problem is that those arnt numbers. those are blocks. theres no mathematical equation there.

i think it is this way:
first 64 Boxes
then you cut through some of them.
on this way you get an additional box somewhere.

if you wouldn'z gut though the boxes the number is the same

sry my english is bad and my math too :P

It's a simple matter of changing the area. Think of it in simpler term: a 2x2 block. It has a perimeter of 8 and an area of 4. If you change the perimeter to be 1x3, it would keep the perimeter of 8 but the new area would only be three. The only reason the animation throws you off is because it starts with a designated number of squares and seems to add one out of nowhere.

no it isn't... the hypotenuse is not straight on the triangle, this tiny bow in the line which is practically imperceptible to the eye over the 13 squares loses a square. so yeah...

that would not add a square. also, it would not fit if was curved.

it would, it is a famous optical illusion google it :D it was on QI, basically they are all slightly bowed to make the a single squares worth of area.

oh ok, I get it. I was thinking why the top right and bottom left corners didn't fit right.

for all of you non-beleivers, this is 100% absolute fact. just spent the last 40 mins trying it down the last box

nope, the lines that are drawn arent straight, there's a tiny gap but added up enough surface to fill one square

o rly? did u actualy try it? in real life? no u probly just looked at the video. so try it out before you talk ****.

The slopes of the trapezoids and triangles do not match
the slope of the trapezoids have a Rise/Run of 2/5
the triangles have a rise/run of 3/8
2/5= 0.4
3/8=0.375
this means that there is a tiny gap between shapes, resulting in about 1 unit

here you can see it, it's dutch but you get the gist
there you go moron, ******* simple math

m1 = 3/8 = 0.375 , Gradient of red & green slope
m2 = 2/5 = 0.4 , Gradient of blue & orange Slope

Seconds Grid: Slope interference between red and orange & blue and green @ (0<x<5).
Yr = m1*5 = 2
AreaRed = 1.875*5*1/2 = 4.6875cm^2

Yo = 0.4*5 = 2
AreaOrange= 5*2*1/2 = 5cm^2

Area lost = AreaOrange - AreaRed = 0.3125cm^2
Area lost * 2 = totalAreaLost = 0.625cm^2

Or in simpler terms, the slopes simply don't match up and the creator of the GIF made them look like they were. Not sure if I calculated it right or all of it, but I can't be bothered spending more than 5 minutes on one piece of content, so I don't really care. :D

Didn't read, but i'll just assume you're correct :)
