What are some examples of dilation?
1 Answer
See below
Explanation:
Here is an example of dilation (also known as scaling).
Dilation is a transformation on the plane when there is a rule that transforms every point to its image as follows.
There is a center of dilation
Every point
(a) point
(b) length
(if
Dilation preserves parallelism between lines.
Dilation results in all segments to change their length by the same factor
Dilation preserves the angles between lines.
Dilation transforms geometric figures into similar ones.
Actually, the definition of similarity is best approached from the position of dilation:
Two geometric objects,
