Answer:
SAS
Step-by-step explanation:
Given
[tex]Triangles\ ABC\ \&\ SRT[/tex]
[tex]A = S\\ BC = RT\\ AB = RS.[/tex]
Required
Select from the given options, which answers the question
The given parameters show that:
There's an equal angle
i.e.
[tex]A = S[/tex] Angle (A)
And equal two sides
[tex]BC =RT[/tex] Side (S)
[tex]AB = RS[/tex] Side (S)
So, we can postulate that SAS exist
Hence: option (b) answers the question
