Answer:
The additional information to show ΔABC ≅ ΔDEF by ASA is
≅
Explanation:
The given parameters in the figure are;
Angle m∠BAC is congruent to angle m∠FDE
Angle m∠ABC is congruent to angle m∠FED
Therefore, in order to show that ΔABC is congruent to ΔDEF, by the Angle-Side-Angle (ASA) rule of congruency, the additional information is the congruency of the included sides between the given angles as follows;
The additional information to show ΔABC ≅ ΔDEF by ASA is
is congruent to
which can be written as
≅
