FLASHCARD QUESTION

Front

What is a dilation in the context of the coordinate plane?

Back

A dilation is a transformation that alters the size of a figure on the coordinate plane by a scale factor, while maintaining the shape and the relative positions of the points.

FLASHCARD QUESTION

Front

What is the scale factor in a dilation?

Back

The scale factor is a number that determines how much a figure is enlarged or reduced during a dilation. A scale factor greater than 1 indicates enlargement, while a scale factor between 0 and 1 indicates reduction.
