Question

If Isometry preserves distance and angle measurement ,which of the following are examples of Isometry?

A)Reflection
B)Translation
C)Both reflection and translation
D)None of the above

Answer 1

C) Both reflection and translation

Explanation:

An isometry of the plane is a linear transformation which preserves length. Isometrics includes rotation, translation , reflection ,glides and the identity map.

A geometry transformation is either rigid or non-rigid

The another name for a rigid transformation is 'isometry'.

The dilation is not isometry
