can anyone explain what's happening here ?

IT Doesn't work!

Curves shmurves!!

I wasn't convinced, so I redrew the thing in cad, to scale, using only thin lines... No curves.

And I get the same result.

I really don't get it.

Your picture is a better example than the original one.

Look at the points where the two triangles meet.

And this is the two triangles overlapping.

Now do you get it ‽

I did it! Interrobang'd!

 

[bettaobsession]

you guys are confusing me!!!!

 

[Cheech]

OK ok ok ... I got it. lol...

there are no curves . .. It's the fact that the triangles themselves are different. The big triangles, not the pieces in them . . . Thanks!


Pretty interesting illusion!

i second that notion

 

[Cheech]

OK so I redrew the first triangle, but in this example, I used a perfect triangle by joining the extremities of the larger triangle. Then I divided it, and copied the pieces to the second drawing, which clearly shows that if the larger triangle is in fact a perfect one, it can't be rearranged in the way the illusion tries to trick us into seeing it.


OK enough geometry for today.

i think that is what i was trying to say?
i am not sure.

why were you doing this?

yep, except I didn't understand until afterwards. lol... Thanks for clearing it up.


why I did it? no reason really. I just like it when things make sense.

Right, technically the larger figure is not a triangle...it is a quadrilateral with one of the angles being nearly 180 degrees.

 

[Coler]

Yep.
