Question

How to I prove that ΔABC=ΔDCB?

Answer 1

see if you can use a congruence theorem

Answer 2

I don't know how to do that

Answer 3

Its okay, look at the two small triangles. look at the given info. and tell me wat sides are equal.

Answer 4

AC=BD ?

Answer 5

yes, and wat other sides are equal

Answer 6

CB= BC

Answer 7

perfect !

Answer 8

so all 3 sides are equal between both the triangles, eh ?

Answer 9

yes!

Answer 10

Thanks!

Answer 11

we prove it like this :-

It is given that, AB = DC , and AC = DB. And CB = BC by reflexive property. Since all 3 sides in one triangle are equal to all 3 sides in another triangle. both the triangles are congruent by SSS congruence.
