Translations

A translation is a transformation that slides a figure along a straight line.
To translate a figure in a coordinate plane, add or subtract the given number of units to the preimage coordinates.
Positive values translate a figure up or to the right.
Negative values translate a figure down or to the left.

Translate the fiugre 2 units up and 1 unit to the left.

See the translation in the image to the right.

Describe the translation from figure A to figure B

See the translation in the figure to the right.
