1. dilation

Dilation is a transformation in geometry that alters the size of a shape, without changing its basic form or proportions. It involves scaling the dimensions of an object either to make it larger (expansion) or smaller (contraction) from a specific point known as the center of dilation, while maintaining the same orientation. The degree of dilation is determined by a scale factor, which can be greater or less than 1.
