Question

Which transformation will map figure H onto figure H'

Answer 1

Are you able to post a picture of the figures?

Answer 2

There you go :) @jim_thompson5910

Answer 3

thanks

Answer 4

I was thinking A but I dont know

Answer 5

so what transformations do you think are going on?

Answer 6

I can't see the choices

Answer 7

Reflection across the y-axis

Vertical translation of 10 units

Vertical translation of 15 units

Reflection across the x-axis

Answer 8

But then it cant be A cause it is shifted

Answer 9

hmm I spot a problem

Answer 10

What is it?

Answer 11

the figure is perfectly symmetrical about its center horizontal axis

Answer 12

so when you reflect it over the x axis, you get H to go to H'

Answer 13

Ohhhhhh I see

Answer 14

that's fine

but...you can also translate it down 10 units to make H land on H'

Answer 15

But it shifts though

Answer 16

so there are 2 possible answers

both are perfectly plausible

Answer 17

Hmmm, I think its B

Answer 18

D is just as likely

Answer 19

so you can see the problem

Answer 20

Yeah, this is tricky!

Answer 21

you'll have to ask your teacher about it

Answer 22

there's no way to determine which one they want

Answer 23

Ok thank you so much for your help!

Answer 24
