Question

Really need help! Decide whether the pattern can be mapped onto itself by a reflection, rotation, translation or glide reflection

Answer 1

what did you get for the first one?

Answer 2

I thought it was reflection...

Answer 3

good, it could also be a translation

Answer 4

how about the second?

Answer 5

glide reflection?

Answer 6

why a reflection?

Answer 7

there is a glide (ie a translation), but I don't see any reflections

Answer 8

thats the only glide option

Answer 9

is there just a translation option?

Answer 10

yes

Answer 11

then go for that, that's what I would do

Answer 12

because

glide reflection = translation + reflection

or

glide reflection = reflection + translation

Answer 13

okay so the second would be translation?

Answer 14

yes

Answer 15

I'm assuming there's only one answer choice per problem right?

Answer 16

yes, so would the third be rotation?

Answer 17

yes a rotation would work here

Answer 18

Thanks would you mind helping me with two more designs?

Answer 19

sure

Answer 20

first one is...

Answer 21

reflection?

Answer 22

yep, about the center vertical line

Answer 23

the second I think would be translation?

Answer 24

no

Answer 25

but a rotation will work (rotate it 180 degrees about the very center point)

Answer 26

oh okay, Thank you!

Answer 27

it might help to print it out, do a trace of it, then rotate and compare

Answer 28

thank you will do!
