@catsarecool1995 you know the difference between concurrency and similarity? We have already proved them to be similar right

anonymous · Answer

Is this using the SAS theorem? =)

ankit042 · Answer

yeah they were proved to be similar by SAS theorm. but now we are looking at concurrency. Think what all things are required to prove triangles are congruent

anonymous · Answer

I think the answer is true. Is that right?

ankit042 · Answer

Two objects are congruent if they have the same dimensions and shape

ankit042 · Answer

Now because they were similar we know that shape is same. But we are not sure about the dimensions

anonymous · Answer

Okie dokie what do we do to figure out those dimensions?

ankit042 · Answer

In the question there is not enough information to conclude anything about dimensions. So you can't be sure about them being congruent hence answer will be false!

Hope you understood the concept

Yes much better, thank you : )
