A dilation requires a center point and a scale factor. Dilations can result in a larger figure or a smaller figure than the pre-image. All of the transformations that we have studied so far in this unit produce images that are congruent to the pre-image. A dilation is another type of transformation where the size does NOT remain the same. A(0,0) B(10,0) C(7,8) 2. Draw the image of ABC with dilation with k = 1 2 3. Compare the perimeter of ABC to A'B'C'. If P(x,y) is the preimage of a dilation with scale factor, k, then The fixed point is the center of the dilation. All of the original distances are multiplied by the same scale factor. For example, triangle $DEF$ is a dilation of triangle $ABC$. The center of dilation is $O$ and the scale factor is 3.

Dec 04, 2020 · A dilation of scalar factor k whose center of dilation is the origin may be written: D k (x, y) = (kx, ky). If the scale factor, k, is greater than 1, the image is an enlargement (a stretch). If the scale factor is between 0 and 1, the image is a reduction (a shrink).

EXAMPLE.--The perimeter of the small to the large also grows by the same scale factor. If the scale factor from the small to the large is s, then the area of the large figure is squared or to the second power times the area of the small figure. Example: 3 to the second power or squared = 9 therefore: Perimeter of A = 16 Area of A = 3 x 5 = 15 A dilationis a transformation that can change the size of a polygon but leaves the shape unchanged.
