Identifying Transformations

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way 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 a dilation?

Back

A dilation is a transformation that changes the size of a figure but keeps its shape the same.

Front

What does it mean to reflect a figure?

Back

To reflect a figure means to flip it over a line, resulting in a mirror image.

Front

What is the center of rotation?

Back

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

Front

How does a translation affect the coordinates of a point?

Back

In a translation, each point of the figure moves the same distance in the same direction, changing its coordinates accordingly.

Front

What is the difference between a rotation and a reflection?

Back

A rotation turns a figure around a point, while a reflection flips it over a line.
