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
Is reflection always an isometry?
No. While it is true for reflection in a straight line, it is not true for other reflections.
Is line reflection a direct isometry?
if there is an even number of line reflections then yes. if there is n odd number of line reflections, then no.
What is isometry that does not change orientation?
It's a transformation that's order of the letters like ABCD of a figure don't change when transformed.
What is two isometries that is an isometry?
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
Is a rotation an isometry?
Yes, a rotation is an isometry.
Which type of isometry is the equivalent of two reflections across intersecting lines?
Rotation
What is theorem 5.12?
Theorem 5.12- A rotation is a composition of two reflections, and hence is an invertible 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.
A preimage and an image are congruent in an isometry?
Yes. Being congruent is part of the definition of an isometry.
Explain why a glide reflection is an isometry?
Because the glide reflection is a combination of two isometries, it is also an isometry.
What is Isometry?
An isometry is a transformation in which the original figure and its image are congruent. Shape remains constant as size increases.
An isometry can be illustrated with a graphing calculator. Which function rule matches the isometry?
(x,y) (-x,-y)
Which transformation is not an isometry?
Dilation.
An isometry is a transformation that preserves?
no
An isometry that does not change orientation?
a transformation
