解析 The image under a dilation with a scale factor of -1 is congruent to the pre-image and is rotated 180^(° ).结果一 题目 How can a dilation produce an image in which the pre-image and the image are two different congruent figures? 答案 The image under a dilation with a scale...
The picture below shows a dilation with a scale factor of 2. This means that the image, A', is twice as large as the pre-image A. Like other transformations, prime notation is used to distinguish the image fromthe pre-image. The image always has a prime after the letter such as A'...
ABC was dilated through the origin with a scale factor ofk. After the dilation, ∆ABC was congruent to its image∆A′B′C′. What do these results show about the value ofk?A:0<k<1B:k>1C:k=1D:k<0 相关知识点: 试题来源: 解析 C None ...
Scale factor is often described using the variable k. The scale factor is typically greater than 0, however, can be negative but results in a new figure that is a rotation about the point of dilation but with the same dilation of the absolute value of that scale factor....

Enlarge triangle ABC with C as the center of dilation and a scale factor of 3. Solution: Step 1:Measure CA. Step 2:Extend the line CA to the point A’ such that CA’ = 3CA. Step 3:Repeat the steps for point B to get B’. ...
that is, a size transformation with a positive scale factor−sends the circle of radius 2 centered at A(2,2) to the circle of radius 3 centered at A′(5,6). What distance does the origin O(0,0), move under this transformation?( )...
A dilation is an enlargement or reduction of an image by a scale factor. We also learned that the center of dilation is a point about which we are dilating an object. The scale factor is the number that each coordinate is multiplied by to get the new image. An enlargement is when the...
