Question

Which two transformations can map Figure 1 onto Figure 2?

reflection across the y-axis followed by translation 10 units down

reflection across the y-axis followed by reflection across x-axis

reflection across the x-axis followed by reflection across y-axis

translation 11 units left followed by translation 10 units down

Answer 1

Definitely reflection followed by translation down. Just look at it!

Answer 2

thats what i thought but i was thinking maybe the 2nd one could be right as well

Answer 3

Good point, could be both. I'd have to sketch it and I'm involved in another problem. Do the reflection across y-axis and then look carefully at the other...

Answer 4

I see a problem.

Answer 5

The bottom of the p'gram 1 is at (6,2)
y reflection would give -6, 2
so both of the first two look wrong b/c they would retain x = -6
Do you see that?

Answer 6

C doesn't work for the same reason.

Answer 7

D doesn't work b/c the shape is different. It is reflected through y.
I think the problem is bad.

Answer 8

I'm not sure what telliot thought was the problem, I think he was right the first time
reflection followed by translation

Answer 9

The problem is that the vertex at 6,2 ends up at x = -5

Answer 10

that's the vertex (5,8) isn't it ?

Answer 11

Arghh..

Answer 12

mwahaha

Answer 13

Dr. Evil where did you come from...

Answer 14

At least all I did was point out that you were correct this time :)

Answer 15

Actually, I believe I have seen mini-me here once or twice :)
