Indicate the method you would use to prove the two Δ's ≅ . If no method applies, enter "none".

None

Here is your answer
[tex]<b>SSS </b>[/tex]
REASON:
SSS congruency states that, if all the three sides of a triangle are respectively equal to the corresponding sides of another triangle then both triangles are said to be [tex]<u>congruent</u>[/tex].
Here, in both triangles
7units=7 units
8units=8units
Middle side is common to both triangles so it is equal.
Hence, both triangles are congruent by SSS
