To locate:Midpoints of
Answer to Problem 17WE
The midpoints of segments
Explanation of Solution
Given information :
A glide reflection maps
Concept used:
In 2-dimensional geometry, a glide reflection is a symmetry operation that consists of a reflection over a line and then translation along that line, combined into a single operation.
A translation moves ("slides") an object a fixed distance in a given direction without changing its size or shape, and without turning it or flipping it.The original object is called the pre-image, and the translation is called the image.
As per the given problem, A glide reflection maps
Below diagram is provided in problem.
To get midpoints of
It seems that the midpoints of segments
For example
After translation,
Say reflection line
The point
Midpoints of segments
Almost lie on the reflection line.
Hence,
The midpoints of segments
