Mar 05, 2010 · C 2 4 The smaller figure above is dilated with a scale factor of 2 and a center of dilation C to produce the larger figure. 11. Translation, Reflection, Dilation, and Rotation (continued) Rotation A transformation in which a figure is rotated around a given point called the center of rotation by a specified degree measure in a specified direction.
The two triangles have been constructed so that all three pairs of sides have the same scale factor. Use the slider to change the scale factor (r). Describe what changes and what stays the same when you change the scale factor: Now use the other slider to change the measure of angle B. Describe what changes and what stays the same.

Dilations are usually measured by their scale factor. Reminder: A scale factor that is greater than one creates a larger image. A scale factor between 0 and 1 creates a smaller figure. Scale Factor = 3 Scale Factor = 1/2

Prove the circles are similar by finding a center and scale factor of a dilation that moves circle Aonto circle B. 20. Practice B 6 - Dolfanescobar's Weblog
You could use a scale factor to solve! In this tutorial, learn how to create a ratio of corresponding sides with known length and use the ratio to find the scale factor. Then, write an equation using the scale factor to find your missing measurement!
The scale factor of a dilation is the ratio of a length in the image to the corresponding length in the original figure. This dilation is centered at the origin, so you can find the image by multiplying the
In the example below, the scale factor of triangle ABC to triangle DEF is 2. This means that the second triangle is 2 times as big. If you multiply a side from triangle ABC by 2, you get the length of the corresponding side of triangle DEF. You can also get 2 as the scale factor by finding the ratios: 12/6 = 2, 16/8 = 2, and 18/9 = 2.

Well they give us the scale factor, and so what it tells us, the scale factor is 5/2. That means that the corresponding lengths will change by a factor of 5/2. So to figure out the length of segment A'E', this is going to be, you could think of it as the image of segment AE. And so you can see that the length of AE is equal to two.

Scale Factor - the ratio of the lengths of corresponding sides of similar figures. Enlargement - when the image (or the new figure) is bigger than the original - happens when the scale factor Dilations. When a figure is dilated, its size is changed by multiplying the length of each side by a scale factor.
