a.
To find:Image of
a.
Answer to Problem 8CE
The image, point
Explanation of Solution
Given:
Translation
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.
Calculation:
As per the given problem
Translation
Hence,
The image, point
b.
To find:Image point
b.
Answer to Problem 8CE
The image of
Explanation of Solution
Given:
The line of reflection is line
Concept Used:
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.
Calculation:
As per the given problem
Translation
Under the reflection in the line
Hence,
The image of
c.
To find:Under glide reflection,
