Scaling.
What is a preimage. (The new figure is called the image.)
Dilation
Its called points maybe
Reflections, translations, rotations.
A rotation.
Dilation is a transformation in which a figure is enlarged or reduced.
It will be as you term it 'horizontal stretch' in which the figure is enlarged or reduced in size.
it means a transformation in which a polygon is enlarged or reduced by a given factor around a given center point.so its an enlargmant or a reduction
In mathematics, dilation refers to a transformation that alters the size of a geometric figure while keeping its shape and proportions intact. It involves scaling the figure up or down from a fixed point known as the center of dilation, using a scale factor that determines how much the figure is enlarged or reduced. Dilation can be applied in various contexts, including geometry and coordinate transformations.
Compare the length of a line common to both, this is the scale value
A figure resulting from a transformation is called an IMAGE
It is the figure before any transformation was applied to it.
a scale drawing.
It is the image from the transformation.
A transformation that slides a figure horizontally is called a translation. A transformation that slides a figure vertically is also called a translation.
