Heng tried to define a reflection across line r. • Any point N on line r maps to itself.

• Any point M not on the line of reflection maps to a point M' such that the midpoint L of MM' is

on liner.

Which counterexample shows that Heng's definition does not fully define a reflection?

Choose 1

Any point N on line r maps to itself.

Step-by-step explanation:

Reflection is one of the examples of solid transformation in which a given point, segment, or figure is flipped over a reference point or line to produce its image. The distance of the object to the reference point or line is the same as the distance of its image to the point or line. And both have the same size, but different orientation.

The option that does not fully define a reflection is; any point N on line r maps to itself, because no image of point N is produced after the operation.

i don't even know how to read that, ill try to do it if you translate it into english.
