Question

1. in the tessellation below, what transformation(s) maps brick a onto brick b?a rotation followed by a reflectiona glide reflectionreflection followed by a translationa rotation followed by a translation

Explanation:

A glide reflection is a combination of a translation (glide) and a reflection over a line parallel to the direction of the translation. Observing Brick A and Brick B, Brick A can be shifted (translated) and then reflected over a line parallel to the translation direction to exactly match Brick B. The other options do not match: rotation would alter the orientation in a way that doesn't fit, and reflection followed by translation or rotation followed by translation/reflection do not produce the exact match seen here.

Answer:

a glide reflection
