Question

Please, some one intelligent here, could help to know, how this two triangles are similar??

Answer 1

the question?

Answer 2

to prove if this two triangle are similar .

Answer 3

maybe I could use ASA to prove?? I not pretty sure

Answer 4

AA , if two angles on triangles equal to two angles of another triangle,they are similar :)

Answer 5

we don't have ASA! AA,SS

Answer 6

If 2 angles are equal then the 3rd must be equal..... but do we know anything about the sides? can have infinitely many triangles with the same 3 angle measures.

Answer 7

exactly

Answer 8

oh right.... we only want them to be similar, not congruent.... :)

so, yeah, you just need to notice that if the 2 angles are the same, then the 3rd one is also.

Answer 9

Similar just means that the angles are all the same. They are the same "shape", not necessarily the same SIZE. :)

Answer 10

yes you are right thanks

Answer 11

and when,
\[\frac{ S _{1} }{ S _{2} } = \frac{ S _{3} }{ S _{4} } = \frac{ S _{5} }{ S _{6} }\]
they are similar :)

Answer 12

got it?

Answer 13

yes thanks a lot guys

Answer 14

you're welcome :)
