Answer 1

TRANSLATION

Answer 2

but wait...

Answer 3

am i wrong?

Answer 4

holy eff.

Answer 5

i dont understand if it is translation... sorry to send a lot of pics

Answer 6

hmm, let me check around and see.

Answer 7

thanks!

Answer 8

p.s.-- i hate geometry with a passion.

Answer 9

so do i only a few more things and im out... then im off to algebra II

Answer 10

ah, algebra II was fun. have fun graphing a crapton though :)

Answer 11

great, something to look forward too.

Answer 12

In geometry, a glide reflection is a type of isometry of the Euclidean plane: the combination of a reflection in a line and a translation along that line. Reversing the order of combining gives the same result. Depending on context, we may consider a reflection a special case, where the translation vector is the zero vector.
The combination of a reflection in a line and a translation in a perpendicular direction is a reflection in a parallel line. However, a glide reflection cannot be reduced like that. Thus the effect of a reflection combined with any translation is a glide reflection, with as special case just a reflection.

Answer 13

^it kinda makes sense....
