What transformation is not a congruent image?
A transformation that is not a congruent image is a dilation. Unlike rigid transformations such as translations, rotations, and reflections that preserve shape and size, dilation changes the size of a figure while maintaining its shape. This means that the original figure and the dilated figure are similar, but not congruent, as their dimensions differ.
Which sequence of transformation produces an image that is not congruent to the original figure?
A translation of 4 units to the right followed by a dilation of a factor of 2
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.
Why does a dilation transform a figure?
A dilation transforms a figure by scaling it proportionally from a fixed center point, known as the center of dilation. This process changes the size of the figure while maintaining its shape and the relative positions of its points. Each point in the original figure moves away from or toward the center of dilation based on a specified scale factor, resulting in a larger or smaller version of the original figure. Thus, dilation preserves the geometric properties, such as angles and ratios of distances.
What is a point with respect to which a figure is dilated?
dilation
A transformation in which a figure and its image are similar?
Dilation
What type of transformation can change the size of an image from the original figure?
Dilation.
What transformation is not a congruent image?
A transformation that is not a congruent image is a dilation. Unlike rigid transformations such as translations, rotations, and reflections that preserve shape and size, dilation changes the size of a figure while maintaining its shape. This means that the original figure and the dilated figure are similar, but not congruent, as their dimensions differ.
A new figure made after a transformation is called?
In mathematical terms, the figure that is made after a transformation is what is known as an image. Prior to the chance, the figure is called the pre-image. Changing into an image can take place after four types of mathematical transformations: translation, reflection, rotation and dilation.
How do you find the scale factor of dilation?
The scale factor is the ratio of any side of the image and the corresponding side of the original figure.
Which transformation does not always result in an image that is congruent to the original figure?
A dilation (or scaling) is a transformation that does not always result in an image that is congruent to the original figure. While translations, rotations, and reflections always produce congruent figures, dilations change the size of the figure, which means the image may be similar to, but not congruent with, the original figure.
Which sequence of transformation produces an image that is not congruent to the original figure?
A translation of 4 units to the right followed by a dilation of a factor of 2

How does the size of an image compare to the original figure undergoes a dilation with a scale factor of one?
A scale factor of one means that there is no change in size.
In a dilation the image is always similar to its pre-image?
Yes, it is.
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 transformation is not an isometry?
Dilation - the image created is not congruent to the pre-image
