Well, isn't it self evident?
Anyway, I think I should yes ^^

So, A is congruent to C because A and C are both congruent to B? Isn't that what you need to prove in the first place?

Ok, here's another version :
We have the 3 geometric figures : A,B,C With the information given: A congruent to B, B congruent to C
So, inversely, we will have :
B congruent to A, because A is congruent to B, so, its inverse must necessarely also be true, because if it wasn't we would a contradiction with the information given to us that A congruent B, but we know that it isn't the case, so the only option left is B is really congruent to A
C congruent to B For the same reason has the above statement.
So, we have 3 geomtric figures congruent, because A is congruent to B, and having proved the inverse of B congruent C, that is, C congruent to B, we see that the two geometric figures(A and C) are also congruent to the same figure (B), and that...

Well, sorry for my mistake in terms, I meant congruent,xD

hi AlAllo
This seems to be a good way to prove this, but your proof is difficult for me to follow because I'm not clear which lines are in which shape.

Show that if a geometric figure is congruent to another geometric figure, which is in its turn congruent to a third geomtric figure, then the first geometric figure is congruent to the third.
