Front

What is the definition of a translation in geometry?

Back

A translation is a transformation that moves every point of a figure the same distance in the same direction.

Front

What are the coordinates of a point after a translation of (x, y) by (a, b)?

Back

(x + a, y + b)

Front

If a point (2, 3) is translated 4 units left and 5 units down, what are the new coordinates?

Back

Front

What is the effect of translating a figure on the coordinate plane?

Back

The shape and size of the figure remain unchanged; only its position changes.

Front

What is the difference between a pre-image and an image?

Back

A pre-image is the original figure before transformation, while an image is the result after transformation.
