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 a rotation a isometry?
Not always
How are the size and the orientation of the triangle affected by the rotation?
The size does not change and the orientation is altered by the extent of the rotation.
Does a reflection change the orientation?
In general, yes.
Is reflection always an isometry?
No. While it is true for reflection in a straight line, it is not true for other reflections.
An isometry that does not change orientation?
a transformation

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.
A preimage and an image are congruent in an isometry?
Yes. Being congruent is part of the definition of an isometry.
Do rotations preserve or change the orientation of the figure?
They change the orientation.
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.
