Answer:
A) SSS
Step-by-step explanation:
In geometry, two figures are congruent if they have the same shape and size. In this case, triangle ACB and triangle DFE are congruent if they have exactly the same three sides and exactly the same three angles.
SSS property (side, side, side) states that two triangles have all three sides equal. This means that:
- Side AC and side DF are equal (marked with one line)
- Side CB and side FE are equal (marked with two lines)
- Side BA and side ED are equal (marked with three lines)
