Which theorem proves that the triangles are congruent?
ddd [48]
Hello!

Looking at the image above, we are given that side BE is congruent to side ED while side AE is congruent to side EC. This can be written as follows:

BE = ED
AE = EC

In this case, ∠1 and ∠2 can be classified as vertical angles. Vertical angles are the two angles on opposite sides of two intersecting lines. These angles are always congruent to one another. Consequently, ∠1 and ∠2 must also be congruent to one another. This can be written as follows:

∠1 = ∠2

We have now proven the congruency of two sides and one angle. Because the angle lies between the two sides, this implies the use of SAS (side-angle-side).

Therfore, the correct answer is B.

I hope this helps!
