Is reflection always an isometry?
No. While it is true for reflection in a straight line, it is not true for other reflections.
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
What is a reflection in geometry?
Reflection of an object is the flip of that subject on a particular line, that is called line of reflection.
How is a line of reflection like a line of symmetry?
A line of reflection and a line of symmetry both show the reverse of an image.
What is the line of reflection in symmetry?
The line of reflection in symmetry is the imaginary line that travels down the line of symmetry. For example, in a square, the line of reflection would be the line down the center of the square, and the line down the diagonal of the square.
Is reflection always an isometry?
No. While it is true for reflection in a straight line, it is not true for other reflections.
Explain why a glide reflection is an isometry?
Because the glide reflection is a combination of two isometries, it is also an isometry.

A blank is an isometry that maps all points of a figure the same distance in the same direction?

Does a isometry preserves orientation?
There are four types of isometries:Reflection - preserves ABCD not OAngle MeasureBetweenessCollinearityDistanceNOT OrientationTranslationRotationGlide Reflection
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.
What is a reflection in geometry?
Reflection of an object is the flip of that subject on a particular line, that is called line of reflection.
A preimage and an image are congruent in an isometry?
Yes. Being congruent is part of the definition of an isometry.
