Answer:
C. ASA
Step-by-step explanation:
The details of the given parameters are;
Angle ∠B of ΔABC is congruent to angle ∠E of triangle ΔDEF,
Angle ∠C of ΔABC is congruent to angle ∠F of triangle ΔDEF
Side
of ΔABC is congruent to side
of triangle ΔDEF
Two angles (∠B and ∠C) and the included side (side
) of ΔABC are congruent to the corresponding two angles and included side (∠D, ∠E and side
) of ΔDEF, therefore, the two triangles are congruent by the Angle-Side-Angle, ASA, rule of congruency
