Translation - French-English - par définition, deux triangles sont semblables si...

"if their angles are two to two congruent"

Hello,

Would it be all right to say:
"if their angles are equal, taken two by two."

or it's wrong?

Madeleine

geometrically speaking, two triangles are said to be similar if two of their "corrosponding" angles are congruent (and thus all of their corrosponding angles are congruent), i dont know what this "two to two" and how it fits here tho

je crois que pour traduir fondamental vers l'arabe dans ce cas le mot le plus approprié c est أَسَاسِيّ

"si leurs angles sont deux a deux congrus "= if their angles are congruents 2 by 2 .
