What is the difference between the scale factor and 6? I am more than satisfied with this app, but after giving solution of two answers it asks for upgradation which means you have to pay money for further sums. First, determine the change in X and Y of the original image. The picture below demonstrations a dilation of $$ \frac{1}{2}$$ Any time that the scale factor is a fraction, the image will get smaller. Take any known side of the scaled triangle, and divide it by its corresponding (and known) side of the second triangle. WebA dilation is a transformation that produces an image that is the same shape as the original, but is a different size. To calculate the dilations with scale factor 3, the new coordinates of the triangle will be: $$ A' \;=\; (3,3) \;,\; B' \;=\; (9,3 0 \;,\; C' \;=\; (3,9) $$. If you want to dilate a 2D shape, assign 2 points and for a 3D shape, choose 3. Lesson 4.3 Card Sort: Matching Dilations on a Coordinate Grid.
