Question

the transformation that has translation and a reflection across a line parallel to the direction of translation is called as __________.

○ parallel reflection

○ glide reflection

○ regular reflection

○ diffused reflection

Explanation:

To solve this, we recall the definitions of each transformation:

• Parallel reflection: Not a standard term for this combination.
• Glide reflection: Defined as a translation (glide) followed by a reflection across a line parallel to the translation direction.
• Regular reflection: Typically just a reflection over a line, no translation.
• Diffused reflection: Related to light scattering, not a geometric transformation here.

So the correct term is glide reflection.

Answer:

B. glide reflection
