Question

1. other than translation, what transformation is used to create this frieze pattern? glide reflection 180° rotation vertical reflection horizontal reflection

Explanation:

A glide reflection is a combination of a translation (sliding) and a reflection. In the frieze pattern, the foot - print motifs are both translated (moved along a line) and reflected (flipped). A \(180^{\circ}\) rotation would turn the motif around a point by half - a - circle, which is not the case here. A vertical reflection would flip the motif over a vertical line, and a horizontal reflection over a horizontal line, but the pattern shows a combination of sliding and flipping (glide reflection).

Answer:

glide reflection
