Question

what type of symmetry is essential in creating wallpaper patterns? a. no symmetry b. translational symmetry c. reflective symmetry d. rotational symmetry if a pattern repeats itself every 5 units along a line, what type of symmetry is this? a. rotational symmetry b. reflective symmetry c. translational symmetry d. inverse symmetry

Explanation:

Wallpaper patterns need repeating. Translational symmetry is about repeating patterns along a line.

Answer:

1. b. Translational symmetry
2. c. Translational symmetry
