What is called a transformation that shrinks or stretch a figure?
A transformation that shrinks or stretches a figure is called a dilation. In a dilation, all points of the figure are moved away from or toward a fixed center point, known as the center of dilation, by a scale factor. If the scale factor is greater than one, the figure is stretched; if it is between zero and one, the figure is shrunk.
What ia a transformation that shrinks or stretches a figure?
A transformation that shrinks or stretches a figure is known as a dilation. In a dilation, each point of the figure is moved away from or toward a fixed point called the center of dilation, by a scale factor. If the scale factor is greater than one, the figure is stretched; if it is between zero and one, the figure is shrunk. This transformation preserves the shape of the figure but alters its size.
What are the invariant points of a dilation?
Invariant points of a dilation are the points that remain unchanged under the transformation. In a dilation centered at a point ( C ) with a scale factor ( k ), the invariant point is typically the center ( C ) itself. This means that when a point is dilated with respect to ( C ), it either moves closer to or further away from ( C ), but ( C ) does not move. Therefore, the only invariant point in a dilation is the center of dilation.
What transformation does not preserve distance and angle measure?
A transformation that does not preserve distance and angle measures is a non-rigid transformation, such as a dilation or a shear transformation. In a dilation, the distances from a center point are scaled, changing the size of the figure but not maintaining the original shape. In a shear transformation, the shape is distorted by slanting it in one direction, altering both distances and angles between points. These transformations result in figures that are not congruent to their original form.
A transformation in which the figure grows larger is called?
A transformation in which the figure grows larger is called dilation. In dilation, every point of the figure is moved away from a fixed center point by a scale factor greater than one. This results in a proportional increase in the size of the figure while maintaining its shape.

In a dilation, all points of the figure are moved away from or toward a fixed center point, known as the center of dilation, by a scale factor.

What is the transformation of C(9 3) when dilated by a scale factor of 3 using the origin as the center of dilation?
It is (27, 9).
What ia a transformation that shrinks or stretches a figure?
A transformation that shrinks or stretches a figure is known as a dilation. In a dilation, each point of the figure is moved away from or toward a fixed point called the center of dilation, by a scale factor.

What are the invariant points of a dilation?
Invariant points of a dilation are the points that remain unchanged under the transformation. In a dilation centered at a point ( C ) with a scale factor ( k ), the invariant point is typically the center ( C ) itself. This means that when a point is dilated with respect to ( C ), it either moves closer to or further away from ( C ), but ( C ) does not move. Therefore, the only invariant point in a dilation is the center of dilation.

A transformation in which the figure grows larger is called dilation. In dilation, every point of the figure is moved away from a fixed center point by a scale factor greater than one. This results in a proportional increase in the size of the figure while maintaining its shape.
Are dialation rigid motion transformation?
Dilation is not a rigid motion transformation; instead, it is a similarity transformation. While rigid motion transformations, like translations, rotations, and reflections, preserve distances and angles, dilation alters the size of a figure by expanding or contracting it from a center point. This change in size means that the shapes remain similar but are not congruent to their original forms.
What is A transformation that is determined by a center point and a scale factor?
A transformation determined by a center point and a scale factor is known as a dilation. In this transformation, all points in a geometric figure are moved away from or toward the center point by a factor of the scale. If the scale factor is greater than 1, the figure enlarges; if it is between 0 and 1, the figure shrinks. This transformation preserves the shape of the figure but alters its size.
What is the transformation of B(4 8) when dilated by a scale factor of 2 using the origin as the center of dilation?
To find the transformation of point B(4, 8) when dilated by a scale factor of 2 using the origin as the center of dilation, you multiply each coordinate by the scale factor. Thus, the new coordinates will be B'(4 * 2, 8 * 2), which simplifies to B'(8, 16). Therefore, point B(4, 8) transforms to B'(8, 16) after the dilation.
What transformation produces a figure that is similar but not congruent?
A transformation that produces a figure that is similar but not congruent is a dilation. In a dilation, a figure is resized proportionally from a center point, resulting in a shape that maintains the same angles but alters side lengths. This means that while the two figures have the same shape, they differ in size, making them similar but not congruent.
How can you find the center of dilation of a triangle and its dilation?
To find the center of dilation of a triangle and its dilation, you can identify a pair of corresponding vertices from the original triangle and its dilated image. Draw lines connecting each original vertex to its corresponding dilated vertex; the point where these lines intersect is the center of dilation. The scale factor can be determined by measuring the distance from the center of dilation to a vertex of the original triangle and comparing it to the distance from the center to the corresponding vertex of the dilated triangle.
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.
