What is an isometry in geometry? An isometry, also called isometric transformation, is a transformation in which a figure and its image are congruent.
1. One example of isometry is when a figure flips. This is called reflection. A real life example of this is a person looking at himself in the mirror.
2. Another example of isometry is when a figure slides to a new location. This is called translation. A real life example of this is a person moving his head up and forward.
3. One more example of isometry is when a figure turns. This is called rotation. A real life example of this is a person bending his head down.
