Answer:
Given that,
To establish that the two triangles are congruent,
Janessa and Ralph list transformations and justifications, as shown in the table.
To find the correct transformation and justification
we have that,
In a reflection transformation, all the points of an object are reflected or flipped on a line called the axis of reflection or line of reflection.
Here, all the points of an object are reflected with the line of inflection y axis.
Hence the correct transformation is Reflection.
A reflection is rigid transformation that preserves distance and angle measure, so the two triangles are congruent.
Therefore, Ralph provide both a correct transformation and a correct justification.
Answer is: Ralph only.
