Explanation

Transformations in Geometry follow definitions and properties:

Key definitions:

1. Translation: slides a figure → preserves distance, angle, and orientation

2. Rotation: turns a figure → preserves distance and angle; orientation may stay or reverse depending on rotation

3. Reflection: flips a figure → preserves distance and angle, reverses orientation

4. Dilation: enlarges/reduces → preserves angles and shape, scales distances

Why important: Knowing properties allows you to predict outcomes and prove congruence or similarity.
