Question

Geometry Help anyone?!....Which transformation will map Figure H onto Figure H’?

A. reflection across the y-axis

B. vertical translation of 10 units

C. vertical translation of 15 units

D. reflection across the x-axis

Answer 1

if you look at the picture which axis is inbetween the two images?

Answer 2

@Christawna~Marie are you there?

Answer 3

the x axis

Answer 4

so the answer is D? ..but why how come its not a translation but rather a reflection?
can you explain please?

Answer 5

if you look in a mirror what do you see?

Answer 6

a relection...but it also looks like a translation...

Answer 7

so in other words...how can I tell the difference?

Answer 8

a translation is when you take something and move it elsewhere so efectivly a reflection is also a translation.

Answer 9

the answer is B. B. vertical translation of 10 units.

It cannot be a reflection, note that H has a vertex at (4,2) and the reflection about X-axis will have vertex at (4,-2) but the figure H prime (the bottom one) has a vertex at (4,-3). Thus on reflection the figures won't overlap. Only way to do that is to slide down the figure above 10 units to the bottom.

Answer 10

it cannot be a reflectio cuz, in mirror if u see, preimage is at same distance from the image. but here thats not the case..

Answer 11

ahhh, many pardons i did not look at the picture in detail.

Answer 12

okay...I see what you mean about the reflection @pitankar and @ganeshie8

Answer 13

it does look like a reflection cuz it has horizontal symmetry.. if it was translated just 9 units down, then its both translation and reflection

Answer 14

okay. well thanks :)

Answer 15

yw! :)
