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. 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. Web5.2 Info Gap: Dilations. Your teacher will give you either a problem card or a data card.

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? 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.

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.

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)
