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.

Similar figures are produced through transformations such as dilation, where a shape is enlarged or reduced by a scale factor while maintaining its proportions. This transformation alters the size of the figure but keeps the angles and the relative dimensions between corresponding sides the same, ensuring that the figures remain similar. Additionally, similar figures can also be obtained through rotations, reflections, and translations, as these transformations preserve the shape and angle relationships.
In a dilation, a figure and its image are similar but not necessarily congruent. The image is a scaled version of the original figure, enlarged or reduced based on a scale factor. The corresponding angles of the original figure and its image remain equal, while the lengths of corresponding sides are proportional according to the scale factor.
A transformation that slides a figure horizontally is called a translation. A transformation that slides a figure vertically is also called a translation.
It is the image from the transformation.
