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.

How do you find the invariant line of a stretch?
To find the invariant line of a stretch, identify the direction in which the stretch occurs. The invariant line is typically the line that remains unchanged during the transformation, often along the axis of the stretch. For example, if stretching occurs along the x-axis, the invariant line would be the y-axis (or any line parallel to it). You can confirm this by observing that points on the invariant line do not change their position under the stretch transformation.
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.
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.

A B C Has coordinates of A(6 7) B(4 2) and C(0 7). Find the coordinates of its image after a dilation centered at the origin with a scale factor of 2.?
To find the image of points A, B, and C after a dilation centered at the origin with a scale factor of 2, you multiply each coordinate by 2. The new coordinates are A'(12, 14), B'(8, 4), and C'(0, 14). Thus, the images of the points after dilation are A'(12, 14), B'(8, 4), and C'(0, 14).

Which properties are preserved under dilation?
Properties such as parallelism, ratio of distances, and the measure of angles are preserved under dilation. This means that parallel lines remain parallel after dilation, the ratio of lengths between corresponding points remains constant, and angles maintain their measures before and after dilation.
How does dilation effect the coordinates of dilated points?
Well this is my thought depending on where the point of dilation is the coordinates of the give plane is determined. The point of dilation not only is main factor that positions the coordinates, but the scale factor has a huge impact on the placement of the coordinates.
Which of the following is not invariant under a glide reflection?
A. Glide reflection b. Orientation of points c. Parallelism of lines d. Areas of polygons
How do you determine the invariant point in a transformation of a relation?
the invarient point is the points of the graph that is unaltered by the transformation. If point (5,0) stays as (5,0) after a transformation than it is a invariant point The above just defines an invariant point... Here's a method for finding them: If the transformation M is represented by a square matrix with n rows and n columns, write the equation; Mx=x Where M is your transformation, and x is a matrix of order nx1 (n rows, 1 column) that consists of unknowns (could be a, b, c, d,.. ). Then just multiply out and you'll get n simultaneous equations, whichever values of a, b, c, d,... satisfy these are the invariant points of the transformation
What is a Zeuthen-Segre invariant?
The Zeuthen-Segre invariant is a numerical invariant of an algebraic surface, denoted by Z(P), where P is a smooth projective surface. It is calculated using the intersection theory of surfaces and is used to distinguish between surfaces in the same deformation class.
How do you use set and get in object-oriented programming?
A set function (or setter) is an object mutator. You use it to modify a property of an object such that the object's invariant is maintained. If the object has no invariant, a setter is not required. A get function (or getter) is an object accessor. You use it to obtain a property from an object such that the object's invariant is maintained. If the object has no invariant, you do not need a getter.
How do you determine invariant points of a graph algebraically?
Invariants are points that remain the same under certain transformations. You could plug the points into your transformation and note that what does in is the same as what comes out. The details depend on the transformation.
