3. Proving Triangles Congruent-SSS, SAS
Sign In
Look at the position of the angle that is marked on the figure.
Not possible.
Therefore, by using the SSS or SAS postulates it is not possible to determine whether the two triangles are congruent.
The relationship given in the exercise is often called Side-Side-Angle(SSA). As a general rule, we cannot use SSA to prove triangle congruence. If given the measurements of the triangle, without proper context, there are two possible lengths for the third side. We can draw an example of this situation.
