Answer 1

you have picture>?

That link goes to nothing but a login screen.

Answer 3

is it two triangle? i think ?

Answer 4

ya

Answer 5

you need side angle side
you see both share the same diagonal side
what do you think you should use for the other side?

Answer 6

when you use SAS, you must have them "in that order" on the triangle. we can conclude that AC = AC because its the same line. we have angle DAC=angle BCA, so, following SAS the next attribute of the triangle we need to use is a side, and it has to be "next" when we go around the triangle. So we must prove AD = BC. SAS would not work if the other piece of info we knew was DC=BA

Answer 7

If two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the triangles are congruent.
