1. Single transformation of a triangle - help :(
Triangle one's points are at:
3,0 3,3 and 1,3
Triangle two:
0,3 3,3 and 3,1

They're crossing each other, looks bit like a right-angled triangle if something dented the diagonal :P

But what is the single transformation which takes triangle one to triangle two?

I guess "rotate the reflected triangle from point 0,3 by 270' anti-clockwise" but I bet I'm wrong ...

Just try to figure out how can (3,0) change to (0,3). The 'x' value of triangle one is the y value of triangle two and the case is similar with the y coordinates.

Same thing happens when transforming (3,3) to (3,3) and (1,3) to (3,1), the x-coordinates change to y-coordinates and the the y-coordinates change to x-coordinates.

See the spoiler if you still can't figure out.
