Translations and Reflections

Front

What is the arrow notation for a shape that is translated 8 units left and 2 units up?

Back

(x, y) --> (x - 8, y + 2)

Front

What is the arrow notation for a translation where the pre-image is solid-lined and the image is dashed-lined, moving 7 units left and 4 units up?

Back

(x, y) --> (x - 7, y + 4)

Front

Reflect the point T(2, -4) over the y-axis. What is the new coordinate?

Back

T' (-2, -4)

Front

Which option represents a reflection across the x-axis?

Back

C

Front

A triangle is translated 4 units right and 3 units down. What is the arrow notation for this translation?

Back

(x, y) --> (x + 4, y - 3)

Front

What is a translation in geometry?

Back

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

Front

What does reflection mean in geometry?

Back

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

Front

How do you reflect a point over the x-axis?

Back

To reflect a point (x, y) over the x-axis, the new point will be (x, -y).

Front

How do you reflect a point over the y-axis?

Back

To reflect a point (x, y) over the y-axis, the new point will be (-x, y).

Front

What is the effect of translating a shape 0 units left and 0 units up?

Back

The shape remains unchanged.
