Maggie claims that there are transformations that preserve the length of the rectangles sides. which of the following could NOT
be used to support Maggie’s claim?
A. a dilation of scale factor 1 through center C
B. a rotation of 90 degrees clockwise about vertex Q
C. a reflection over the side RS
D. a vertical stretch of scale factor 2 through center C
1 answer:
Answer:
D. a vertical stretch of scale factor 2 through center C
Step-by-step explanation:
Given
Claim that there are transformations that keep the length of a rectangle
Required
Which can not be used to prove this claim
From the list of given options: option (a) to (c) can be used by Maggie to back up her claim because:
(a) Scale factor of 1 do not alter the length
(b and c) Rotation and Reflection do not change the length
However
(d) doubles the length of the rectangle
Hence, (d) is correct.
