They are the same for pairs of corresponding sides.
What is a preimage. (The new figure is called the image.)
With a scale factor of 1, the image is exactly the same size as the original object.
Dilation
Pick a vertex of the original shape.Draw a perpendicular to the given line.Double the length of this perpendicular. The end point is the image of the original vertex.Repeat for all other vertices of the original shape.Join the vertices of the image.
Image over preimage(original)
The number used to multiply the lengths of a figure to stretch or shrink it to a similar image. If we use a scale factor of 3, all the corresponding lengths in the original side lengths will be multiplied by three.
The original figure is called the pre-image. After the transformation it becomes the image.
What is a preimage. (The new figure is called the image.)
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
Isometry
Image
Dilation.
9
That's referred to as the scale.
the number used to muliplpy the lengths of a figure to stretch or shrink it to a similar image.
