Raquel is the best, she is so beautiful , she is so nice to people and she is a very good Basketball player. i would love to meet or be Raquel one day
What else can I help you with?
When the preimage and image are congruent the transformation is called an isometry true or false?
True. An isometry is a transformation that preserves distances and angles, meaning that the preimage and image are congruent. Examples of isometries include translations, rotations, and reflections, all of which maintain the shape and size of geometric figures.
What is the composition of two isometries?
Preservation of Length
Does an isometry preserves orientation?
An isometry is a transformation that preserves distances between points, and it can either preserve or reverse orientation. For example, a rotation is an isometry that preserves orientation, while a reflection is an isometry that reverses orientation. Therefore, whether an isometry preserves orientation depends on the specific type of transformation being applied.
Is a rotation a isometry?
Not always
Is reflecting a congruence transformation?
YES ---- Explanation: An isometry is a distance-preserving mapping. . Geometric figures which can be related by an isometry are called congruent. Reflection preserves distance so it is an isometry. It reverses orientation so it is called an indirect orientationl
Explain why a glide reflection is an isometry?
Because the glide reflection is a combination of two isometries, it is also an isometry.
Is a composition of any two isometries always is an isometry?
Yes, that is correct.
What is isometries rigid transformations?
I think "isometries" and "rigid transformation" are two different names for the same thing. Look for "isometry" on wikipedia.

True. An isometry is a transformation that preserves distances and angles, meaning that the preimage and image are congruent. Examples of isometries include translations, rotations, and reflections, all of which maintain the shape and size of geometric figures.

Is a rotation an isometry?
Yes, a rotation is an isometry.
Is a translation an Isometry?
Yes, translation is part of isometry.
What is an isometry?
A isometry is a transformation where distance (aka size) is preserved. In a dilation, the size is being altered, so no, it is not an isometry.
Which type of isometry is the equivalent of two reflections across intersecting lines?
Rotation
How did Luigi Bianchi shape geometry?
In 1898, Bianchi worked out the Bianchi classification of nine possible isometry classes of three-dimensional Lie groups of isometries of a (sufficiently symmetric) Riemannian manifold. Bianchi knew this is essentially the same thing as classifying, up to isomorphism, the three-dimensional real Lie algebras.
Does an isometry preserves orientation?
An isometry is a transformation that preserves distances between points, and it can either preserve or reverse orientation. For example, a rotation is an isometry that preserves orientation, while a reflection is an isometry that reverses orientation. Therefore, whether an isometry preserves orientation depends on the specific type of transformation being applied.
A preimage and an image are congruent in an isometry?
Yes. Being congruent is part of the definition of an isometry.
