Question

Geometry help please! Justify if two triangles are congruent

Answer 1

A. All we know is that B is midpoint of AC.
Is that enough to prove the triangles are congruent?

Answer 2

No, I don't think that is enough to prove the triangles are congruent

Answer 3

AB is congruent to BC because of the definition of a midpoint
BD is congruent to BD because of the reflexive property

Answer 4

you would have to prove that angle CBD and angle ABD are congruent...
It would have to be a given point that it's perpendicular
Which it's not, so you no, you cannot prove they're congruent with SAS
