Hey guys, I need your help to discover how can this be possible?? this figure has the same figures in both triangles but in one of them has a blank square. Really, I tried to solve this doubt but i still not understanding how can this happen.

it's like that candy bar trick a bunch of retards fell for, except this is real. it has just rearranged the shapes of which have different areas causing them to take up different amounts of spaces this time now.

>> No.7024014

The hypotenuse isn't straight, it's convex in one and concave another.

compute the slopes of the line segments forming the two triangles

>> No.7024019

the red triangle and the green triangle don't have the same slope.

>> No.7024022

>>7024009
the gradient of green shape is 2/5 and gradient of the red shape is 3/8. Hence they are not triangles with the same shape and the whole shape is actually a quadrilateral

>> No.7025163

there is a 1x1 invisible quadrilateral in the first image that you can't see because it's on the outside of the shape.
When you rearrange the shape, the invisible 1x1 becomes more visible.

>> No.7025167

It's not a real triangle so you can't measure its area by multiplying cathetuses. The missing square is the difference between slightly bulged and slightly caved hypotenuse.

>> No.7025190

It's because when the figures are moved around, the area of the figure stays the same while the perimeter changes.

It's two lines, at angle 0.38pi and 0.35pi if I didn't miscount. Basically, they look close, but they aren't part of the same straight line.

I don't know where these people come from, but it can't be a good sign of what's to come.

This is correct. The "hypoteneuses" of these two triangles aren't actually single straight lines - they are two lines. The smallest angle of the dark green triangle is 22 degrees while the smallest angle of the red triangle is 20.5 degrees.

speak for yourself, I spent an hour trying to see how to do this

>> No.7027620

>>7025226
Work it out.

Slope=rise/run right?
Red triangle's hypotenuse rises 3, runs 8
Dark green triangle's hypotenuse rises 2 runs 5.

3/8 < 2/5

So clearly there's a bend, and it get switched from concave (low slope to high slope)
to convex (high slope to low slope).

Just take a look a the gradient of the faux hypotenuse. Clearly they differ. There's even a plot behind for easy reference.
