Nora says that the shapes shown below are translations of each other. Judy says that the transformation is a glide-reflection. In two or more complete sentences, explain who is correct.

Accepted Solution

Translation is the transformation that deals with moving an object from its initial position to another position without any alteration in the objects size or orientation.

A glide reflection is a transformation which involves refrection of an object across a line and translation of the object along the same line.

From the figure above it can be seen the shape on top is obtained by moving the shape under 6 units to the right and 7 units up.

There is no refrection of any sort between the two figures.

Therefore, Nora is correct.
