To find:Whether distance is invariant under translation.
a.

Answer to Problem 11WE
Yes, distance is invariant under translation.
Explanation of Solution
Given:
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.An invariant is a property of a mathematical object which remains unchanged, after operations or transformations of a certain type are applied to the objects.
Calculation:
As per the given problem
Translation
Distance between points is invariant under translation.
i.e.
Hence,
Distance is invariant under a translation.
b.
To find:Whether

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.An invariant is a property of a mathematical object which remains unchanged, after operations or transformations of a certain type are applied to the objects.
Calculation:
As per the given problem
Translation
Angle measure between points is invariant under translation.
i.e.
Hence,
Angle measure is invariant under a translation.
c.
To find:Whether area is invariant under translation.
c.

Answer to Problem 11WE
Yes, area is invariant under translation.
Explanation of Solution
Given:
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.An invariant is a property of a mathematical object which remains unchanged, after operations or transformations of a certain type are applied to the objects.
Calculation:
As per the given problem
Translation
Area of
i.e. All the corresponding sides are equivalent & angle formed at all the points are same.
Hence,
Area is invariant under a translation.
d.
To find:Whether orientation is invariant under translation.
d.

Answer to Problem 11WE
Yes, orientation is invariant under translation.
Explanation of Solution
Given:
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.An invariant is a property of a mathematical object which remains unchanged, after operations or transformations of a certain type are applied to the objects.Orientation is how the relative pieces of an object are arranged.
Calculation:
As per the given problem
Translation
Slope of
Hence,
Orientation is invariant under a translation.

- Can someone help me with this please?arrow_forwardMariela is in her classroom and looking out of a window at a tree, which is 20 feet away. Mariela’s line of sight to the top of the tree creates a 42° angle of elevation, and her line of sight to the base of the tree creates a 31° angle of depression. What is the height of the tree, rounded to the nearest foot? Be sure to show your work to explain how you got your answer.arrow_forward1arrow_forward
