A preimage and an image are congruent in an isometry?
Yes. Being congruent is part of the definition of an 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- A triangle and a line of reflection are shown.Which of the following shows the preimage and the image?
bottom right
What is the relationship between the line of reflection and the segment connecting a point on the preimage with its corresponding point on the image?
perpendicular bisector (student @ jfk middle)-Miami,Florida(BEAT)
what- Sally wants to use a heart pattern as wallpaper for her cell phone.Which of the following shows the preimage and image?
bottom right
A shape that results from a transformation of a figure known as the preimage?
Yeah, that's right it is called a preimage.
Identify the orientation where the image has same orientation as the preimage?
The answer is in the question! The orientation is the same as the preimage! Same = Not different.
Describe the difference between an image and a preimage?
A preimage is a transformed irritated or changed image. Such as a flipped triangle
Can a point or a line segment be its own preimage?
A point or a line segment can be a preimage of itself because a line can be reflected or rotated.
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).
the figure shows the preimage?
true
What transformation that has the orientation as the preimage?
Translation.
