Translations and Reflections Practice Flashcard

Front

What is a translation in geometry?

Back

A translation is a type of transformation that moves every point of a shape a certain distance in a specified direction.

Front

If point A is at (-3, 3) and is translated 4 units right and 5 units down, what is the new location of A'?

Back

(1, -2)

Front

What does a 'slide' mean in geometry?

Back

A 'slide' refers to a translation.

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a shape over a line, creating a mirror image.

Front

If a shape is reflected over the x-axis, how do the coordinates change?

Back

The y-coordinates change sign; (x, y) becomes (x, -y).

Front

If a shape is reflected over the y-axis, how do the coordinates change?

Back

The x-coordinates change sign; (x, y) becomes (-x, y).

Front

What is the result of reflecting the point (4, -1) over the y-axis?

Back

(-4, -1)
