A dilation is a type of transformation that changes the size of the image. The scale factor, sometimes called the scalar factor, measures how much larger or smaller the image is. Below is a picture of a dilation with a scale factor of 2. This means that the image, A', is twice as large as the pre-image A. Like other transformations, prime notation is used to distinguish the image fromthe pre-image. The image always has a prime after the letter such as A' .

What else can I help you with?
Transformation that proportionally reduces or enlarges a figure?
Dilation is a linear transformation that enlarges or shrinks a figure proportionally. It is also referred to as uniform scaling in Euclidean geometry.
What does dilation mean in math?
To increase in size. You use the dilation property in coordinative graphs.
Is a scale factor of 1 a dilation?
No a scale factor of 1 is not a dilation because, in a dilation it must remain the same shape, which it would, but the size must either enlarge or shrink.
Which transformation is not an isometry?
Dilation.
Different types of geometry?
Euclidean geometry, non euclidean geometry. Plane geometry. Three dimensional geometry to name but a few
What is the meaning of a dilation in geometry?
It is increasing the size.
What does the word dilation in geometry mean?
Getting bigger. Dilation factor of 2, then it would get twice the size.
A geometry student uses a dilation tool in his geometry software to do an identity transformation on an octagon. The screen is shown.Is this an identity transformation Answer yes or no?
no
When you enlarge something on a photocopy machine is that image a dilation?
Yes, when you enlarge an image on a photocopy machine, it can be considered a dilation. Dilation in geometry refers to the transformation that changes the size of a figure while maintaining its shape and proportions. In the case of photocopying, the enlarged image retains the same shape and relative dimensions as the original, making it an example of dilation.
What does the math term dilation mean?
In mathematics, dilation refers to a transformation that alters the size of a geometric figure while keeping its shape and proportions intact. It involves scaling the figure up or down from a fixed point known as the center of dilation, using a scale factor that determines how much the figure is enlarged or reduced. Dilation can be applied in various contexts, including geometry and coordinate transformations.
How does dilation relate to similarity?
Dilation is a transformation that alters the size of a figure while maintaining its shape and proportions, which directly relates to similarity in geometry. When a figure undergoes dilation, the resulting image is similar to the original figure, meaning corresponding angles remain the same and corresponding sides are in proportion. This property of dilation ensures that similar shapes can be created by scaling up or down without distorting their fundamental characteristics. Thus, dilation is a key method for establishing similarity between geometric figures.
Transformation that proportionally reduces or enlarges a figure?
Dilation is a linear transformation that enlarges or shrinks a figure proportionally. It is also referred to as uniform scaling in Euclidean geometry.
What is translation in geometry?
A translation is when a shape slides. There are three other transformations other than this: * rotation * dilation * reflection. During translation, an object changes its position but not orientation.
What Term means the expansion of?
Dilation
What does dialation mean in math context?
In mathematics, dilation refers to a transformation that alters the size of a geometric figure while maintaining its shape and proportions. This involves resizing the figure by a scale factor relative to a fixed point known as the center of dilation. A scale factor greater than one enlarges the figure, while a scale factor between zero and one reduces it. Dilation is commonly used in geometry to study similar figures and their properties.
Does an enlargement of a photograph represent a dilation or a rotation?
Dilation
