Homothety

Homothety, also known as dilation or similarity transformation, is a geometric transformation that alters the size of a figure while maintaining its shape and relative proportions. It can be described as a scaling transformation around a specific point, known as the center of homothety. In formal terms, a homothety can be defined by the following characteristics: 1. **Center of Homothety**: This is a fixed point in the plane from which the scaling occurs.
