This also would help you.

These are kinds of reflections: 
Reflection across x-axis:		(x, y) > (x, -y)
Reflection across y-axis:		(x,y) > (-x, y)
Reflection over origin:			(x,y) > (-x,-y)
Reflection over line y=-x:		(x,y) > (-y,-x)

|dw:1478037778809:dw|If you double every coordinate, the figure will get a lot bigger, yes?

So no congruence in this case.
Hopefully the illustration helps.
