Transformation in geometry is the process of altering the position, size, or orientation of geometric figures through specific operations known as transformations. These changes allow us to study and understand the relationships between shapes and spaces, contributing to various mathematical applications and real-world scenarios. Transformation plays a crucial role in geometry, providing a framework for exploring how figures can be manipulated while retaining certain properties.

2. Types of Transformations:

In geometry, three primary types of transformations are translation, rotation, and reflection. Each transformation has distinct properties and applications. Translation involves shifting a figure from one position to another without changing its size or shape. Rotation, on the other hand, entails turning a figure around a fixed point, while reflection creates a mirror image over a line. These transformations form the foundation for more complex geometric operations, offering valuable insights into the dynamic nature of shapes in both theoretical and practical contexts.

Translation: Shifting Positions in Space:

Translation, a crucial concept in transformation geometry, involves the displacement of a geometric figure from one location to another without altering its size, shape, or orientation.
