The transformation is a/an ……………, if k = 1, where k is the scale factor of a given size transformation.
identity transformation
reduction
enlargement
map
Answer
If k = 1, the resulting figure (image) is congruent to the original figure (object), meaning it has the same size and the same shape. This specific transformation is called an identity transformation because it maps the object onto itself.
Hence, option 1 is the correct option.
