No, a figure and its reflection image are congruent. It is like our reflections in a mirror. Hope I answered your question!
Length of image = Length of original*Scale factor = 10*8 = 80 yards.
The original figure and its image must be of the same size and the same orientation. That is, you should be able to get from the original to the image by moving the shape along the x-axis and the y-axis and nothing else. However, if the shape has rotational or reflective symmetry, there is no way that you can be sure that it has not been rotated or reflects (as appropriate).
A translation of 4 units to the right followed by a dilation of a factor of 2
A transformation that creates a mirror image of the original image is called a reflection. This transformation flips the image across a line called the axis of reflection, creating a mirror image that is a flipped version of the original.
The original figure is called the pre-image. After the transformation it becomes the image.
Figures are congruent if and only if they are related by a translation, reflection, or rotation, or some combination of these transformations.
The figure that results from some transformation of a figure. It is often of interest to consider what is the same and what is different about a figure and its image EX: original Image
What is a preimage. (The new figure is called the image.)
Isometry

A figure has linear symmetry when after reflection, the image looks exactly the same as the original
To rotate a shape using reflection, you would typically mirror the shape across a line (such as the x-axis, y-axis, or a custom line). The reflection operation then creates the rotated shape as a mirror image of the original shape.
