Question

Which transformations map the strip pattern onto itself?

A) a horizontal translation and a 180 rotation
B) a horizontal translation and a reflection across a vertical line
C) a horizontal translation and a glide reflection
D) a horizontal translation only

Answer 1

B. a horizontal translation and a reflection across a vertical line

Answer 2

Answer: D) a horizontal translation only

Explanation:

A) The image create by a horizontal translation and a 180 degrees rotation : pdpdpdp

B) The image create by a horizontal translation and a reflection across a vertical line : bqbqbqb

C)The image create by a horizontal translation and a glide reflection : qbqbqbq

D)The image create by a translation only will : dpdpdpd

Therefore, the transformation map the strip pattern onto itself is a horizontal translation only.
