WebA dilation is a transformation in which each point on a figure moves along a line and changes its distance from a fixed point. The fixed point is the center of the dilation. All of the original distances are multiplied by the same scale factor. For example, triangle is a dilation of triangle . The center of dilation is and the scale factor is 3.

WebIt's easier to divide points by two than it is to do a length just like that. When we divide the points, then we also divide the length. For example, let's say we have a square with side length 2 and vertices at (2, 2), (0, 2), (2, 0), and (0, 0). If we shrink this square by 2, we divide each point by 2. phillyd earbuds

WebStrand: Geometry & Measurement. Benchmark: 7.3.2.4 Translations & Reflections on a Coordinate Grid. Graph and describe translations and reflections of figures on a coordinate grid and determine the coordinates of the vertices of the figure after the transformation. For example: The point (1, 2) moves to (-1, 2) after reflection about the y -axis. WebA dilation is a transformation in which each point on a figure moves along a line and changes its distance from a fixed point. The fixed point is the center of the dilation. All of the original distances are multiplied by the same scale factor.

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 WebPerform a dilation on the coordinate plane. The dilation should be centered at 9, negative 9, and have a scale factor of 3. So we get our dilation tool out. We'll center it-- actually, so it's already actually centered at 9, negative 9. We could put this wherever we want, but let's center it at 9, negative 9.

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. http://mathletenation.com/content/dilations-coordinate-grids
