Answer:
Option 3rd Dilation is the answer.
Step-by-step explanation:
Isometry is the transformation that ever changes the shape of the figure or size of the figure.
So, Reflection does not change shape or size
So an isometry
Translation and rotation also does not change shape or size if the figure
Hence a isometry
Dilation changes size by shrinking or enlarging
Hence Not isometry.
Therefore option 3rd is correct.
Answer:
dilation
Step-by-step explanation:
Recall the meaning of isometry
In Geometry, an isometric geometric transformation (or isometry) is a shape-preserving transformation (movement) in the plane or in space.
Hence the isometric transformations can be reflection, rotation and translation and sometimes also combination of any two or all three.
But dilation means the sizes are either enlarged or shrunk to get a similar figure
Example is photograph of a man, the man will appear proportionally small in the photo
Hence isometry cannot be for dilation since sides in the image cannot be congruent to that of original.
SO answer is dilation
