Transformations (Rotations, Reflections, Translations)

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 are the coordinates of point D (-7, -1) after reflecting across the y-axis?

Back

(7, -1)

Front

What are the coordinates of point D (-7, -1) after reflecting across the x-axis?

Back

(-7, 1)

Front

What is a translation in geometry?

Back

A translation is a transformation that moves a figure from one location to another without changing its size or orientation.

Front

What are the coordinates of point C (-2, -2) after reflecting across the y-axis?

Back

(2, -2)

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point at a certain angle.

Front

What are the coordinates of point A (3, 4) after translating 3 units right and 2 units down?

Back

(6, 2)

Front

What is the effect of reflecting a point across the x-axis?

Back
