11) SSS
The Side Side Side (SSS) theorem states that if three given sides of one triangle are equal to the three sides of another triangle, both triangles are congruent.
Since we are given two equal sides (VC = DC) and one common side(CE), to prove this SSS theorem, the additional information required is to indicate the third side of both triangles are equal (VE = DE).
We have the figure below:
Where:
VC = DC
CE = CE
The additional information required is:
VE = DE
ANSWER:
VE = DE
