WebDilations on a Square Grid. Preparation Lesson Practice. View Student Lesson. Problem 1. Triangle \(ABC\) is dilated using \(D\) as the center of dilation with scale factor 2. The image is triangle \(A’B’C’\). Clare says the two triangles are congruent, because their angle measures are the same. Do you agree? WebThe radial lines give rays from the center of the grid which help find the dilated image of points on those rays. The circles provide a way to measure the distance of points from the center of dilation. In this lesson, students apply dilations to points with no grid. WebOn graph paper, sketch the image of quadrilateral PQRS under the following dilations: The dilation centered at R with scale factor 2. The dilation centered at O with scale factor 1/2. The dilation centered at S with scale factor 1/2. The diagram shows three lines with some marked angle measures. the phoenix finance

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. For example, suppose … 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).
