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.
The input of a transformation on the coordinate plane is called the "preimage." The preimage is the original figure before any transformation, such as translation, rotation, reflection, or dilation, is applied to it. After the transformation, the resulting figure is referred to as the "image."
