Important Terms & Definitions
- Preimage: the figure prior to the transformation.
- Image: The figure after the transformation.
- Isometry: a transformation that preserves congruence. In other words, a transformation in which the image and preimage have the same side lengths and angle measurements. The following transformations maintain their mathematical congruence.
- On the other hand,a dilation is not an isometry because its image is not congruent with its pre-image.
