Translations

Front

What is a translation in mathematics?

Back

A translation is a transformation that moves an object by sliding it from one position to another without changing its shape, size, or orientation.

How do you translate a point on a coordinate plane?

Back

To translate a point, you add or subtract values from its coordinates. For example, translating point P(2, 3) 3 units right and 2 units up results in P'(5, 5).

What does it mean to translate a shape 5 units right and 3 units up?

Back

It means to move every point of the shape 5 units to the right along the x-axis and 3 units up along the y-axis.

How do you describe the translation of a shape from one position to another?

Back

You describe the translation by specifying the direction (up, down, left, right) and the distance moved in each direction.
