OpenStudy (amistre64):

OpenStudy (amistre64):
what is a transition?
OpenStudy (wintersuntime):
It's translation
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

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 ?
