Lesson slides for 'Draw an image of a dilation with a negative scale factor' In this lesson you will learn how to draw an image of dilation with a negative scale factor by using the center of dilation at the origin on the coordinate plane. (Slides used in the main video lesson in PowerPoint format.) Understand properties of dilations. a. Verify the properties that result from that dilations given by a center and a scale factor. b. Verify that a dilation produces an image that is similar to the pre-image. KY.HS.G.10 Apply the properties of similarity transformations to establish the AA criterion for two triangles to be similar. KY.HS.G.11 Comprehensive National Football League news, scores, standings, fantasy games, rumors, and more To answer this problem, we remember that the scale factor for a dilation can be calculated by comparing corresponding lengths on the object and its image. We can divide any length on the image, which we can think of as a new length, by the corresponding length on the object, which we can think of as an original length.Find the scale factor. Classify the dilation as an enlargement or a reduction. A. scale factor The fraction is 1 over 3.; reduction B. scale factor 4; enlargement C. scale factor 3; enlargement D. math. line y=3x-1 is transformed by a dilation with a scale factor of 2 and centered at (3,8). 1) Write the ratio of point A to point B that expresses the distance of point along the segment write as PART to WHOLE 2) Calculate the Rise & Run from point A to point B 3) Find the value of the Rise and Run using the ratio that partitions the segment! 4) Locate the point P that corresponds to the Rise and Run. Comprehensive National Football League news, scores, standings, fantasy games, rumors, and more Scale Factor Notes: Explore Video The notes portion of the lesson gives students an opportunity to get a grasp on what scale factor is, and why it is acceptable to drop the units when using scale factor. Additionally, students get an opportunity to work out problems involving scale factor. mapped to circle B by a dilation with center (0, 6) and scale factor 3. So circle A and circle B are similar. B. Circle C with center (0, –3) and radius 2 is similar to circle D with center (5, 1) and radius 5. The scale factor 0.25 is less than 1, so the dilation is a(n) enlargement / reduction . 20. Image length 5 scale factor ∙ original length, so image height 5 ? , or cm. Know Need Plan Coordinates of vertices: P(2, 0), Z( , ), and G( , ) Center of dilation: ( , ) Scale factor: Coordinates of the images of the vertices Substitute the coordinates The amount of scaling is given by the scale factor (greater than zero) If the scale factor is less than 1, the figure is reduced and it is sometimes called a contraction If the scale factor is... State the translation rule and the scale factor of dilation. Question 20 options: A) To obtain C′, circle C is translated to the right three units and down two units and is dilated with a scale factor of one. B) To obtain C′, circle C is translated to the right three units and down two units and is dilated with a scale factor of two. dilation is called an enlargement. If the scale factor is less than 1, the new figure is smaller than the original figure.This type of dilation is called a reduction.Any dilation of a figure results in changes to the perimeter and area of the figure. Effect of Dilation on Perimeter Whenever a figure is dilated by a scale factor, the perimeter ... The scale factor 0.25 is less than 1, so the dilation is a(n) enlargement / reduction . 20. Image length 5 scale factor ∙ original length, so image height 5 ? , or cm. Know Need Plan Coordinates of vertices: P(2, 0), Z( , ), and G( , ) Center of dilation: ( , ) Scale factor: Coordinates of the images of the vertices Substitute the coordinates This video shows show to dilate a triangle on the coordinate plane by a scale factor of 1/2 and by a scale factor of 2/3. Graph the image of the given triangle under a dilation with a scale factor of −2 and center of dilation (0, 0) . to graph the triangle, select the "polygon" tool and draw the triangle by plotting each vertex in order until it lands back on the first vertex. do not retrace any sides. you may use the "move" tool to move your image if you needed. Circle M can be mapped onto circle N by a reflection across _____ and a dilation about the center of circle M by a scale factor of _____ 7. A translation is applied to ∆ & 1 ) to create ∆ &′ 1′ )′. Let the statement ( T, U)→( =, >) describe the translation. Definition of Scale Factor in the Definitions.net dictionary. Meaning of Scale Factor. What does Scale Factor mean?
