Transformations Review (no dilations)

Front

What is a translation in geometry?

Back

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

Front

What is the pre-image in a transformation?

Back

The pre-image is the original figure before any transformation has occurred.

Front

What is the image in a transformation?

Back

The image is the new figure that results from a transformation.

Front

How do you translate a point (x, y) 5 units to the right and 3 units down?

Back

The new coordinates will be (x + 5, y - 3).

Front

If a trapezoid is translated 8 units down and 5 units to the right, what are the changes in its coordinates?

Back

Each point of the trapezoid will have its y-coordinate decreased by 8 and its x-coordinate increased by 5.

Front

What are the coordinates of point X after translating it 3 units to the left and 9 units down from (1, 4)?

Back

The new coordinates will be (-2, -5).

Front

What is the effect of translating a figure on its size and shape?

Back

Translation does not change the size or shape of a figure; it only changes its position.

Front

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

Back

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

Front

How do you determine the translation vector for moving a figure?

Back

The translation vector is determined by the change in x (horizontal movement) and the change in y (vertical movement).

Front

What is the notation used to denote the image of a point after a transformation?

Back

The image of a point is often denoted with a prime symbol, such as A' for the image of point A.
