Hi lux, and thanks.
But I prefer to find solutions for such tasks by thinking. So I won't look at this link until I found how to solve it.(maybe after a long period of time I'll give up, because i cannot think about triangles and shapes all the time :))
The angles of the red and green triangles seems to be the same.
I give up for now, I need to sleep.
P.S. Why the hell Laura found Arc with his superluminal travels and mysterious triangles.

(joking)
Now I'l be dreaming only of triangle and different shapes rearrangements.

Hi transdimensional, thanks.
But I won't look at your link also :), I'll try to think more about tomorrow.
I'll make a paper triangles.
P.S. My Firefox, while i was on the way of posting what i wrote under the quotes of transdimensional, just can't load the forum page while everyting else can. :) maybe it was some sort of clue for me to think more about and not to read the new posts

I'm posting from google chrome. :)
Good night(or day) for everyone
