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

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.

the distance from any point on the parabola to the focus is the exact same as the distance from that point to the directrix.

if you could provide answer choices that might allow me to answer the question easier if my above answer isn't an option! (:
