Question

In ∆ and ∆, AB = DE, ∠A = ∠D. The two triangles will be congruent by SAS congruence if

Answer 1

Answer:

AC = DE

For triangle to be congruent by SAS axiom two of the sides and the included angle of the triangles must be equal.

Given AB=DF and ∠A=∠D

No for △ABC≅△DFE by SAS axiom we need AC=DE

Answer 2

Answer:

For the triangles to be congruent by SAS axiom we need two sides and included angle of given triangles to be equal.

Given: AB=FD and ∠A=∠D

Now from the figures, we can say that we need the second pair of sides which is AC and DE according to the given definition.

So for given triangles to be congruent by SAS criteria

we need AC=DE
