What transformation is not an isometry?
Dilation - the image created is not congruent to the pre-image
A mapping for which the original figure and its image are congruent?
Isometry
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.
What is Isometry?
An isometry is a transformation in which the original figure and its image are congruent. Shape remains constant as size increases.
Which type of transfoemation does not necessarily result in the image being congruent to the preimage?
An enlargement transformation
Which of the following properties refers to the corresponding side lengths of the preimage and image in an isometry?
distance
Is preimage and image are congruent in a translation?
true
What transformation is not an isometry?
Dilation - the image created is not congruent to the pre-image
What type of transformation are the pre-image and the image congruent figures?
isometry
A mapping for which the original figure and its image are congruent?
Isometry
Is a preimage and image are always congruent in a reflection?
Yup
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.
What is Isometry?
An isometry is a transformation in which the original figure and its image are congruent. Shape remains constant as size increases.
A preimage and image are congruent in a rotation always sometimes or never?
Sometimes
Which type of transfoemation does not necessarily result in the image being congruent to the preimage?
An enlargement transformation
Dilation is a transformation whose preimage and image are A. similar B. adjacent C. complementary D. congruent?
similar
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).
