Transformations Unit Review

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way to produce a new shape.

Front

Name the three main types of transformations.

Back

Translation, Reflection, Rotation.

Front

What is a translation?

Back

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

Front

What is a reflection?

Back

A reflection is a transformation that flips a shape over a line, creating a mirror image.

Front

What is a rotation?

Back

A rotation is a transformation that turns a shape around a fixed point at a certain angle.

Front

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

Back

To reflect a shape over the x-axis means to flip it so that the y-coordinates of the points change sign.

Front

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

Back

To reflect a shape over the y-axis means to flip it so that the x-coordinates of the points change sign.

Front

What is the result of a 90-degree clockwise rotation?

Back

A 90-degree clockwise rotation turns a shape around a point, moving points in a circular path.

Front

What is the difference between rigid and non-rigid transformations?

Back

Rigid transformations preserve the shape and size of a figure, while non-rigid transformations may change the size or shape.

Front

What is the composition of transformations?

Back

The composition of transformations is applying two or more transformations in sequence to a shape.
