Transformations Review

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape to create a new shape.

Front

What are the four main types of transformations?

Back

The four main types of transformations are translation, rotation, reflection, and dilation.

Front

What does it mean to translate a shape?

Back

To translate a shape means to slide it from one position to another without changing its size, shape, or orientation.

Front

What is a rotation in geometry?

Back

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

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 dilation in geometry?

Back

Dilation is a transformation that changes the size of a shape by a scale factor, either enlarging or reducing it.

Front

What is a scale factor?

Back

A scale factor is a number that describes how much a shape is enlarged or reduced during a dilation.

Front

What does it mean if a dilation has a scale factor less than one?

Back

If a dilation has a scale factor less than one, the shape is reduced in size.

Front

What are congruent shapes?

Back

Congruent shapes are shapes that are the same size and shape, but may be in different positions or orientations.

Front

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

Back

Rigid transformations (like rotations, reflections, and translations) preserve size and shape, while non-rigid transformations (like dilations) change size.
