Translations, Reflections, Rotations

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 are the coordinates of point B' after rotating point B(6,5) 180° about the origin?

Back

(-6,-5)

Front

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

Back

Reflect over the y-axis.

Front

What is the angle of rotation for a 270° counterclockwise rotation about the origin?

Back

270°.

Front

What is the result of a transformation called?

Back

Image.

Front

How do you translate a shape 2 units left and 4 units up?

Back

Subtract 2 from the x-coordinate and add 4 to the y-coordinate.

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

What are the coordinates of point A' after reflecting point A(3,4) over the x-axis?

Back

(3,-4).

Front

What is a rotation in geometry?

Back

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

Front

What are the coordinates of point C' after rotating point C(-2,3) 90° counterclockwise about the origin?

Back

(3,2).
