Weekly Flashcardizz #8: Translations and Reflections

Front

What is a reflection in geometry?

Back

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

Front

What does the transformation (x, y) --> (-x, y) represent?

Back

Reflect over the y-axis.

Front

What does the transformation (x, y) --> (x, -y) represent?

Back

Reflect over the x-axis.

Front

How do you find the coordinates of a point after reflecting over the x-axis?

Back

Change the sign of the y-coordinate.

Front

If point K is at (5, 2), what are the coordinates after reflecting over the x-axis?

Back

(5, -2).

Front

What does a translation of 3 units to the right and 2 units down look like in coordinate form?

Back

(x + 3, y - 2).

Front

If rectangle T’E’X’S’ is the image after a translation, how do you find the original coordinates?

Back

Subtract the translation values from the image coordinates.

Front

What is the result of translating a point 5 units down and reflecting it across the y-axis?

Back

The point moves down and then flips horizontally.

Front

Which quadrant is represented by coordinates (-5, -2)?

Back

Quadrant III.

Front

What is the effect of translating a figure 5 units left and 3 units up?

Back

The x-coordinate decreases by 5 and the y-coordinate increases by 3.
