Rigid Transformations

Front

What is a rigid transformation?

Back

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

Front

What happens to the sides and angles of a shape during a reflection?

Back

The sides and angles do not change.

Front

What is the result of reflecting a shape over the y-axis?

Back

The x-coordinates of the points of the shape change sign, while the y-coordinates remain the same.

Front

What is the term for the new figure after a transformation?

Back

Image.

Front

What type of transformation is a flip over a line?

Back

Reflection.

Front

If a shape in Quadrant 1 reflects over the x-axis, which quadrant will the reflection be in?

Back

Quadrant 4.

Front

If a shape in Quadrant 2 reflects over the y-axis, which quadrant will the reflection be in?

Back

Quadrant 1.

Front

What is a translation in geometry?

Back

A transformation that moves every point of a shape the same distance in the same direction.

Front

What is a rotation in geometry?

Back

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

Front

How do you determine the angle of rotation?

Back

By measuring the angle between the original position and the new position of the shape.
