the two triangles are congruent?? or anything like that stated?

anonymous · Answer

there congruent i just need to know the distance?

apoorvk · Answer

ohkay, if they are congruent, then FE = AC. okay with this?

anonymous · Answer

Yes.

apoorvk · Answer

Now do you know how to find the distance between two points/coordinates? something like a 'distance formula' - any faint memories?

anonymous · Answer

no, sorry :( can you show me?

apoorvk · Answer

Hmm, no probs. read this, this is what you need here:

For two points, say P(x$_1$,y$_1$) and B(x$_2$,y$_2$) distance PQ between them is:
$$PQ = \sqrt{(x_1-x_2)^2 + (y_1-y_2)^2}$$

Can you apply this to points A(0,1) and C(3,2) according this^, and find out distance AC?
