Translations, Reflections, and Rotations Flashcard - Duggan

Front

What is a translation in geometry?

Back

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

Front

What are the coordinates of a point after a translation of 3 units right and 2 units up from (4, 5)?

Back

(7, 7)

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 new coordinates of point (3, 4) after reflecting across the y-axis?

Back

(-3, 4)

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point, called the center of rotation.

Front

What are the coordinates of point (2, 3) after a 90-degree rotation counterclockwise around the origin?

Back

(-3, 2)

Front

What does it mean to reflect a shape across the x-axis?

Back

To reflect a shape across the x-axis, you change the sign of the y-coordinate of each point.

Front

What are the new coordinates of point (5, -2) after reflecting across the x-axis?

Back

(5, 2)

Front

What is the effect of translating a shape 4 units left?

Back

Each point of the shape will have its x-coordinate decreased by 4.

Front

What are the coordinates of point (6, 1) after a translation of 4 units left and 2 units down?

Back

(2, -1)
