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 is a translation?

Back

A translation is a transformation that slides a figure from one position to another without turning it.

Front

What is a rotation?

Back

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

Front

What is a reflection?

Back

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

Front

What is dilation?

Back

Dilation is a transformation that changes the size of a figure but keeps its shape, using a scale factor.

Front

What is a pre-image?

Back

The pre-image is the original figure before any transformation is applied.

Front

What is an image in transformations?

Back

The image is the new figure that results from applying a transformation to the pre-image.

Front

What is the center of rotation?

Back

The center of rotation is the fixed point around which a figure rotates during a transformation.

Front

What does it mean to slide a figure?

Back

To slide a figure means to perform a translation, moving it to a different location without changing its shape or orientation.
