Unit 6-Rigid Transformations

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 happens to a point (x, y) when it is reflected over the x-axis?

Back

The point (x, y) becomes (x, -y) when reflected over the x-axis.

Front

What is the result of reflecting the point A(-2, 2) over the x-axis?

Back

A'(-2, -2) is the result of reflecting A(-2, 2) over the x-axis.

Front

What is a 90 degrees clockwise rotation?

Back

A 90 degrees clockwise rotation turns a point around the origin (0,0) to the right by 90 degrees.

Front

What is the result of rotating the point B(3, 2) 90 degrees clockwise?

Back

B'(2, -3) is the result of rotating B(3, 2) 90 degrees clockwise.

Front

What is the difference between translation and rotation?

Back

Translation moves a figure without changing its orientation, while rotation turns a figure around a point.

Front

How do you translate a point (x, y) right by 2 and down by 5?

Back

The new point will be (x+2, y-5).

Front

What is the result of translating the point A'(-2, 2) right by 2 and down by 5?

Back

The new point will be (0, -3).

Front

What does it mean to reflect a figure over the y-axis?

Back

Reflecting over the y-axis changes the sign of the x-coordinate of each point in the figure.

Front

What is the result of reflecting the point C(4, -3) over the y-axis?

Back

C'(-4, -3) is the result of reflecting C(4, -3) over the y-axis.
