Question

Which triangles are congruent and what is the sequence of transformations that maps one figure to the other

Answer 1

Congruent traingles means that one shape can become another using turns, flips and/or slides

If we look at triangle QRS and EDF, both are of the same size.

To convert triangle QRS into EDF we need to rotate QRS 90º clock-wise and flip over respect x axis.

The two other triangles are non congruent.
