WebTo perform a dilation, we need a center of dilation, a scale factor, and a point to dilate. In the picture, P is the center of dilation. With a scale factor of 2, each point stays on the same ray from P, but its distance from P doubles: Figure 2.1.2. 3 WebSquare grids can be useful for showing dilations. The grid is helpful especially when the center of dilation and the point(s) being dilated lie at grid points. Rather than using a ruler to measure the distance between the points, we can count grid units. WebHow to Perform Dilations. Step 1. Identify the center of dilation. Imagine this as the fixed location of the projector. Step 2. Identify the original points of the polygon. Step 3. Identify the scale factor . Step 4.

7.3.2B Translations & Reflections on a Coordinate Grid

WebTo perform a dilation on a coordinate plane, you need to know two pieces of information. First, you need to know the scale factor, or magnitude of the enlargement or reduction. Second, you need a center of dilation, or reference point from which the dilation is generated. In this resource, you will investigate more properties of dilations. WebHighlight that coordinates allow us to unambiguously provide the location of a polygon’s vertices. In addition, reinforce the idea that in order to perform a dilation, we need to know the scale factor and the center of dilation. The coordinate grid again provides an efficient means to communicate the center of dilation.

WebFirst we have to know the correct rule that we have to apply in this problem. Step 2 : Here, triangle is dilated for the scale factor "k = 2". So, the rule that we have to apply here is (x, y) -------> (kx , ky) Step 3 : Based on the rule given in step 1, we have to find the vertices of the dilated triangle A'B'C' Step 4 : (x, y) -----> (kx, ky) WebIn this lesson, they work on a coordinate grid and use the coordinates to communicate precisely the information needed to perform a dilation. Students use the info gap structure. The student with the problem card needs to dilate a polygon on the coordinate grid. In order to do so, they need to request the coordinates of the polygon’s vertices ...

WebA dilation is a type of transformation that changes the size of the image. The scale factor, sometimes called the scalar factor, measures how much larger or smaller the image is. Below is a picture of each type of dilation (one that gets larger and one that gest smaller). Example 1 The picture below shows a dilation with a scale factor of 2.
