Answer:
(C)SAS rule
Explanation:
Given: Two triangles △MNP and △ABC, PN=BC, ∠MNP=∠ABC and NM=BA.
To prove:△MNP ≅ △ABC
Solution:
From △MNP and △ABC, we have
PN=BC(Given in the figure)
∠MNP=∠ABC (Given in the figure)
and NM=BA (Given in the figure)
Thus, by SAS rule of congruency,
△MNP ≅ △ABC.
Hence proved.
Therefore, the rule used is SAS, thus option (C) is correct.
