Question

In $△ABC$ and $△DEF$, $AB=FD$ and $\angle A=\angle D.$ The two triangles will be congruent by $SAS$ axiom, if:

• A. $BC=EF$
• B. $AC=DE$
• C. $AC=EF$
• D. $BC=DE$

Answer 1

The correct option is B $AC=DE$

$SAS=$ If two pairs of sides of two triangles are equal in length, and the included angles are equal in measurement, then the triangles are congruent.

Here, $AB=FD$,

$\angle A=\angle D$

So, $AC=DE$

Hence, option B is correct.
