Question

what are the reflection and translation for the glide reflection shown? sketch the intermediate image.
choose the correct answer below.
a.
b.

Explanation:

Step1: Understand glide reflection

A glide reflection is a composition of a reflection and a translation. The translation is parallel to the line of reflection.

Step2: Analyze the orientation

When we reflect a figure, its orientation (clock - wise or counter - clock - wise) changes. Then we translate it. In option A, the orientation of the intermediate image (after reflection) and the final image (after translation) is not consistent with the properties of glide reflection.

Step3: Check the direction of translation

In option B, first, we reflect the pre - image over a line (the orientation changes as expected for a reflection). Then we translate the reflected image. The translation is parallel to the line of reflection.

Answer:

B.
