Can someone be nice enough to help me please ?

OpenStudy (anonymous):

what is your question?

OpenStudy (wintersuntime):

Is it possible to show a congruence between ABC and A'B'C using only one translation and one reflection? explain.

OpenStudy (anonymous):

Any image?

OpenStudy (wintersuntime):

i could take a picture

OpenStudy (wintersuntime):

hh

|dw:1432001697045:dw|

OpenStudy (wintersuntime):

Its on a graph

OpenStudy (wintersuntime):

the question is Is it possible to show a congruence between ABC and A'B'C using only one translation and one reflection? explain.

OpenStudy (wintersuntime):

u there ?

OpenStudy (wintersuntime):

hello

OpenStudy (wintersuntime):

need help

OpenStudy (anonymous):

The answer is yes, now explaining I'm not sure how..

OpenStudy (anonymous):

yes

OpenStudy (wintersuntime):

why is it yes ?

OpenStudy (anonymous):

can you take a picture of the exercise?

OpenStudy (wintersuntime):

ok

OpenStudy (anonymous):

i think its no Q-Q

OpenStudy (anonymous):

well, if the picture is the original, it seems no, but if it is a sketch not drawn to scale it may be yes.

OpenStudy (anonymous):

or yes Q-Q....

OpenStudy (anonymous):

but its no

OpenStudy (anonymous):

i think

OpenStudy (anonymous):

-nods-

OpenStudy (anonymous):

i think so too

OpenStudy (wintersuntime):

sorry its lagging

OpenStudy (wintersuntime):

OpenStudy (wintersuntime):

Does that help

OpenStudy (amistre64):

how would you go about this?

OpenStudy (amistre64):

what is a transition?

OpenStudy (wintersuntime):

It's translation

OpenStudy (amistre64):

oh good, not that we have the proper word, what does it mean?

OpenStudy (amistre64):

** now that we have ...

OpenStudy (wintersuntime):

the process of moving something from one place to another

OpenStudy (anonymous):

u-umsss Q.Q could you guys be kind enough to help me later? >O<

OpenStudy (amistre64):

good, so if we move a'b'c' so that a = a' we have unmoved it.... can we then form a line for reflection?

OpenStudy (wintersuntime):

yes

OpenStudy (amistre64):

|dw:1432003161897:dw| then since we can undo a translation and a reflection, then we can show that its possible to redo it

OpenStudy (wintersuntime):

so it is possible

OpenStudy (amistre64):

we could have moved it such that b' = b , or c' = c or something inbetween, but i choose that for simplicity

OpenStudy (amistre64):

yep

OpenStudy (wintersuntime):

Could you help me with the second question please ?

OpenStudy (amistre64):

maybe, im only so smart during the day ...

OpenStudy (wintersuntime):

Describe a sequence of rigid motions that would prove a congreuence between ABC and A'B'C

OpenStudy (wintersuntime):

*congruence

OpenStudy (wintersuntime):

I wish I was smart ughh
