Backto school…
a)Move the corner points A,B,E andF ofthe original picture. Are you able to
dragall these points with the mouse? If no, which one can’t be dragged
and why?
Point F can't be modified, it is already fully defined and can not me
modified.
b)Move the line of reflection. What do you notice about the angles
between the segments connecting the corresponding corner points and
the line of reflection?
If you move the reflection behind the original picture the angles change
to 90 degrees.
