What is a translation in geometry?

Back

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

How do you represent a translation mathematically?

Back

A translation can be represented as (x, y) -> (x + a, y + b), where 'a' is the horizontal shift and 'b' is the vertical shift.

What is the image of a figure?

Back

The image of a figure is the result of a transformation applied to the original figure, known as the pre-image.

What is the effect of translating a triangle 5 units to the right?

Back

Each vertex of the triangle moves 5 units to the right, changing their x-coordinates.

If triangle A'B'C' is translated to triangle ABC, what does this imply?

Back

It implies that the positions of the vertices of triangle A'B'C' have been shifted to the positions of the vertices of triangle ABC.

How do you find the new coordinates after a translation?

Back

Add the translation values to the original coordinates: (x + a, y + b).

What is the difference between pre-image and image?

Back

The pre-image is the original figure before transformation, while the image is the figure after transformation.
