Which transformation will produce a similar but not congruent shape?
A transformation that produces a similar but not congruent shape is a dilation. In a dilation, a shape is resized either larger or smaller while maintaining its proportional dimensions, meaning the angles remain the same but the side lengths change. This results in a shape that is similar to the original but not congruent, as congruent shapes have identical sizes and dimensions.
What is change of origin and change of scale?
Translation and dilation.
What is a transformation that changes the size of a figure but not its shape?
scale Or Dilation
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.
How do you dialate a shape by 3?
To dilate a shape by a factor of 3, multiply the coordinates of each vertex of the shape by 3. For example, if a vertex is at (x, y), after dilation it will be at (3x, 3y). This process enlarges the shape while maintaining its proportions and the center of dilation, which is typically the origin (0,0) unless specified otherwise.

What does k mean in dilation?
In dilation, "k" refers to the scale factor that determines how much a shape is enlarged or reduced. If k is greater than 1, the shape is enlarged; if k is between 0 and 1, the shape is reduced. The dilation is centered at a specific point, often called the center of dilation, which affects the positioning of the transformed shape. Thus, "k" directly influences the size and proportion of the original figure.

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.

What is diolation?
dilation is to change or shrink an object.
What properties are not preserved by a dilation?
Dilation transformations do not preserve distances between points, angles, or the orientation of figures. While they do maintain the shape of geometric figures and the relative proportions between their sizes, the actual lengths of sides and the overall size change according to the dilation factor. Therefore, properties like congruence and the specific measurements of sides are not preserved.

What transformation does not result in a congruent figure?
A transformation that does not result in a congruent figure is a dilation. Dilation changes the size of a figure while maintaining its shape, meaning the resulting figure is similar but not congruent to the original. Unlike congruence, where figures remain identical in size and shape, dilation alters dimensions, making the figures proportional but different in scale.
Are dilation rigid motion transformation?
No, dilation is not a rigid motion transformation. Rigid motion transformations, such as translations, rotations, and reflections, preserve distances and angles. In contrast, dilation changes the size of a figure while maintaining its shape, thus altering distances between points. Therefore, while the shape remains similar, the overall dimensions are not preserved.
