What else would need to be congruent to show that ABC= ADEF by SAS? A. ZCE ZF
B. BC = EF
O C. ZA= ZD
D. AC = DF

The correct option is;

c. ∠A ≅ ∠D

Step-by-step explanation:

The given information are;

Therefore, for Side Angle Side, SAS, condition of congruency, we have;

The included angle should be congruent that is ∠C ≅ ∠D

Two triangles, triangle ABC and triangle XYZ for example, having two adjacent sides, AB and AC in triangle ABC and XY and XZ in triangle XYZ of corresponding length such that AB ≅ XY and AC ≅ XZ and also having congruent included angles between the two sides (∠A ≅ ∠X), the two triangles are said to be congruent.
