Transformations Review

Front

What is a rigid transformation?

Back

A transformation that preserves distance and shape, including translations, rotations, and reflections.

Front

What is a non-rigid transformation?

Back

A transformation that does not preserve distance, such as dilation.

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 reflection in geometry?

Back

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

Front

What is a rotation in geometry?

Back

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

Front

What is dilation in geometry?

Back

A transformation that alters the size of a shape by a scale factor, either enlarging or reducing it.

Front

What does a scale factor greater than 1 indicate in dilation?

Back

It indicates an enlargement of the shape.

Front

What does a scale factor less than 1 indicate in dilation?

Back

It indicates a reduction of the shape.

Front

What is the effect of reflecting over the x-axis?

Back

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