Solution

The correct option is B
AAA Congruency

Out of the options given to us, AAA Congruency is one congruency which can’t be used for checking the construction of triangles because even if you take up the simplest example of an equilateral triangle, we know that all the three angles of the equilateral triangle are 60° each but we can have an infinite no. of such triangles if we don’t know about the length of the side of the triangle.

So, it is not possible to take up AAA Congruency as a test for construction, all others are possible.
