How do you find the scale factor of a dilation?
Image over preimage(original)
A transformation in which a figure and its image are similar?
Dilation
Describe the difference between an image and a preimage?
A preimage is a transformed irritated or changed image. Such as a flipped triangle
The original figure in a transformation?
What is a preimage. (The new figure is called the image.)
What are the coordinates for an image on a dilation with a center at the origin?
it is nothing
Dilation is a transformation whose preimage and image are A. similar B. adjacent C. complementary D. congruent?
similar
How do you find the scale factor of a dilation?
Image over preimage(original)
Why is a dilation not an isometry?
Because the image is not the same size as the preimage. To do a dilation all you do is make the image smaller or larger than it was before.
Is a preimage and image are always congruent in a reflection?
Yup
A preimage and image are congruent in a rotation always sometimes or never?
Sometimes
A transformation in which a figure and its image are similar?
Dilation
What are dilations in math?
Dilations are a geometric transformation that results in the image being similar to the preimage.
What are the three types of dilations in math?
The three types of dilations are an enlarged image (the image is larger than the preimage), a reduced image (the image is smaller than the preimage) and an equal image (the image is the same size as the preimage).
Describe the difference between an image and a preimage?
A preimage is a transformed irritated or changed image. Such as a flipped triangle
What is true about the resulting image of a scale factor 3 dilation?
The image is a similar shape to that of the original.
How can the orientation of the image compare with the orientation of the preimage?
The relationship between the orientation of the image and preimage depends on whether the transformation is a reflection or a rotation (or both).
Is preimage and image are congruent in a translation?
true
