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).
it is called a transformation this answer was answered by: Emma Shroades
Length of image = Length of original*Scale factor = 10*8 = 80 yards.
No, a figure and its reflection image are congruent. It is like our reflections in a mirror. Hope I answered your question!
A translation of 4 units to the right followed by a dilation of a factor of 2
Rotational symmetry.
It still has the same weight. Even turned or reflected the weight/mass remains the same.
The original figure is called the pre-image. After the transformation it becomes the image.

The image of a vertex at (x, y) would be (-y, x).
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 dilation (or scaling) is a transformation that does not always result in an image that is congruent to the original figure. While translations, rotations, and reflections always produce congruent figures, dilations change the size of the figure, which means the image may be similar to, but not congruent with, the original figure.
