Answer:
ASA Triangle Congruence Theorem.
SAS Triangle Congruence Theorem.
Step-by-step explanation:
From the diagram:
Angle: Angle A is congruent to Angle D.
Side: AC is congruent to DF
Angle: Angle C is congruent to Angle F.
Therefore, we can say in the first instance that the two triangles are congruent by ASA Triangle Congruence Theorem.
Similarly:
Side: CA is congruent to FD
Angle: Angle A is congruent to Angle D.
Side: AB is congruent to DE
We can also say that the two triangles are congruent by SAS Triangle Congruence Theorem.
