dilations
Openings becoming larger
Dilations are instances of expanding or widening.
In medicine, dilation of the pupils or cervix refers to their enlargement, whether natural or induced.
In mathematics, a dilation is a transformation that enlarges or reduces a figure while preserving its shape and proportions.
The term appears most often in technical contexts: The doctor noted bilateral pupil dilations or We studied geometric dilations in class.
