The answer is for this mathematical equation is: B)4
Answer:
D. AC ≅ DF
Step-by-step explanation:
According to the AAS Theorem, two triangles are considered congruent to each other when two angles and a mon-included side of one triangle are congruent to two corresponding angles and a corresponding non-included side of the other.
Thus, in the diagram given:
<A and <B in ∆ABC are congruent to corresponding angles <D and <E in ∆DEF.
The only condition left to be met before we can conclude that both triangles are congruent by the AAS Theorem is for a mon-included side AC to be congruent to corresponding non-included side DF.
So, AC ≅ DF is what is needed to make both triangles congruent.
