Answer:
Transformation that produces an image that is the same shape but different size is known as Dilation.
Explanation:
There are many types of translations.
1. Rotation
2. Reflection
3. Translation
4. Dilation
We know that rotation, reflection and translation are rigid transformation. It means these transformation can not effect the size of the preimage.
Dilation represents the enlargement and compression of the figure according to the scale factor k.
If |k|>1, then it represent enlargement and if |k|<1, then it represent compression.
Therefore the transformation that produces an image that is the same shape but different size is known as Dilation.
