Two types of dilations Enlargement Reduction Dilations Scale factor - The amount of change written as a ratio To find the new coordinates, multiply the original coordinates by the scale factor. To determine the amount of the dilation, you need to know the SCALE FACTOR. The SCALE FACTOR is the constant by which youʼll enlarge or reduce a figure. For example, this figure has the coordinates (−8, 4); (0, 8); (8, 4); (−8, −4); (8, −4); (0, −8). We want to DILATE this figure by a scale factor of 1 ## 4 Answer: The scale factor of dilation is 2:1 Step-by-step explanation: You can see that the sides of the blue triangle are of lenght 4 and 3, and for the red triangle, the lenghts are 8 and 6 (so the lenghts are doubled) A scale factor is a number by which a quantity is multiplied, changing the magnitude of the quantity. Scale factors are often used in geometric contexts, as part of figure models, and more. The larger penguin model above is 3 times larger than the smaller penguin; To change the larger penguin into the smaller one, we would use a scale factor of .
Dilation with Scale Factor. Scale Factor is defined as the ratio of the size of the new image to the size of the old image. The center of dilation is a fixed point in the plane. Based on the scale factor and the center of dilation, the dilation transformation is defined. If the scale factor is more than 1, then the image stretches. -The triangle pre-image is closer to the point of dilation than the image. -The value of the scale factor, 6, is greater than 1.
