- The center of dilation is a fixed point in the coordinate plane where we can measure the distances of a shape’s vertices. For example, we consider the quadrilateral □ABCD and the point X which will be our center of dilation: The distances between the vertices of the quadrilateral are given by their distance from the point X:

Given a point on the pre-image, ( x 1, y 1), and a corresponding point on the dilated image, ( x 2, y 2) , and the scale factor, k, the location of the center of dilation, ( x o, y o) is ( x o...

Why isn't the center of dilation C?
It is a point where a dilation is based off of. For example: if a center of dilation is the center of a circle with radius 5 and is under a dilation with a scale factor 2, then the radius would be 10.

- The dilation is from N to N' the only way to get there is to "expand" the triangle not "shrink" it
- If you draw an imaginary line from each of the corresponding points of the two figures. The center would be the point that all the lines converge at.
- The triangle isn't shrinking. Instead, it is growing. So the obvious answer is point D because the scale factor is greater *than* 1. Also remember...
- In order to find the center of dilation, (𝑥₀, 𝑦₀), we need to know the coordinates of the point that is dilated, (𝑥₁, 𝑦₁), the coordinates of i...
Dilations are a way to stretch or shrink shapes around a point called the center of dilation. The amount we stretch or shrink is called the scale factor. If the scale factor is greater than 1, the shape stretches. If it's between 0 and 1, the shape shrinks.

Given a point $(x, y)$ and a center of dilation $(h, k)$ with a scale factor of r, the coordinates of the dilated point $(x’, y’)$ can be found using the following formulas: $x’ = h + r(x – h)$
Oct 27, 2023 · Step-by-step Guide: Dilations. 1. Identifying the Center of Dilation: The point about which the figure dilates. If it’s the origin, the dilation is easier to visualize, but any point can serve as the center. 2. Determining the Scale Factor: Denoted by \ (k\), the scale factor indicates the magnitude of dilation.
If the center of dilation is located at a point X(-10,0), and the scaling factor is given by k=3, sketch the plot of the scaled circle. Solution: We first begin by illustrating the given. From the given radius and center of the circle, we can plot the shape as well as the center of dilation as shown:
The resizing happens from a point called the center of dilation. It is the center of dilation from which the objects/figures are expanded or contracted. In the figure shown below, the triangle is enlarged from the center of dilation which is marked as 'R'.
