What is the difference between a translation and a reflection?

Back

A translation slides a figure without changing its orientation, while a reflection flips it over a line.

What is the transformation rule for translating a point (x, y) 5 units left and 2 units down?

Back

What does it mean for a transformation to preserve orientation?

Back

It means that the order of points and their arrangement remains the same after the transformation.
