Answer:
Rotation, then reflection, then translation
Step-by-step explanation:
The sequence of three rigid transformations that is used to map Triangle ABC onto TriangleA"B"C" are what we called ROTATION ,REFLECTION AND TRANSLATION
ROTATION can be defined as the process or waysbin which an object tend to rotate about a fixed point without the object changing either its size or shape.
REFLECTION occur in a situation where an object is been flipped across a line without the object changing either its size or shape.
TRANSLATION can be defined as the process or ways of sliding a figure in any or various direction without the figure changing either its size or shape .
