In this case, to flip any of the points to map
up accurately to the other points, we would have to do a transformation of reflection
about the y-axis. The reason behind this is that out of other transformation
process, we can only achieve the image of triangle ∆A’B’C’ through reflection.
Dilation will not work since it only changes
the size of the object. The shape and position will not affected.
A translation will not work because although
the shape can move, it still needs to flip to achieve triangle ∆A’B’C’.
A rotation will also not work because when you
rotate it, the shape will still not map over the new one.

reflect triangle ∆ABC about the y-axis.</span></span>
