Answer the following statement(s) true (T) or false (F)

1. If A'B' is the image of AB under a translation, then A'B' = AB . 2. If ?ABC is translated to ?A'B'C', then the area of ?ABC may be twice the area of ?A'B'C'. 3. If point O is the center of a size transformation and A' is the image of A, then OA'/OA is called the scale factor of the size transformation. 4. If ?A'B'C' is the image of ?ABC under a size transformation, then ?A'B'C-?ABC. 5. A combination of a size transformation and an isometry is a similitude.
