Rigid Transformations Practice

Front

What is a rigid transformation?

Back

A rigid transformation is a transformation that preserves the shape and size of a figure, including translations, rotations, and reflections.

Front

What are the rotation rules for 180° clockwise?

Back

The rotation rule for 180° clockwise is (x, y) → (-x, -y).

Front

What are the coordinates of a point A(3, 4) after a 180° rotation about the origin?

Back

A'(-3, -4).

Front

What is the reflection rule for reflecting a point across the x-axis?

Back

The reflection rule across the x-axis is (x, y) → (x, -y).

Front

What are the coordinates of a point B(-2, 5) after reflecting across the y-axis?

Back

B'(2, 5).

Front

What is the reflection rule for reflecting a point across the y-axis?

Back

The reflection rule across the y-axis is (x, y) → (-x, y).

Front

What are the coordinates of a point C(1, -3) after reflecting across the line y = x?

Back

C'(-3, 1).

Front

What is the rotation rule for 270° clockwise?

Back

The rotation rule for 270° clockwise is (x, y) → (y, -x).

Front

What are the coordinates of a point D(4, -2) after a 270° rotation about the origin?

Back

D'(-2, -4).

Front

What is the effect of a translation on a point?

Back

A translation moves a point a certain distance in a specified direction without changing its orientation.
