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

What are the four main types of transformations?

Back

Translation, Rotation, Reflection, and Dilation.

Front

Define reflection in geometry.

Back

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

Front

What does it mean to rotate a shape?

Back

To rotate a shape means to turn it around a fixed point, called the center of rotation.

Front

What is translation in geometry?

Back

Translation is a transformation that slides a shape from one position to another without changing its size, shape, or orientation.

Front

What is the result of a transformation called?

Back

The result of a transformation is called the image.

Front

What is the pre-image in a transformation?

Back

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

Front

What does a 90° clockwise rotation do to a shape?

Back

A 90° clockwise rotation turns the shape 90 degrees to the right around a center point.

Front

What does a 90° counterclockwise rotation do to a shape?

Back

A 90° counterclockwise rotation turns the shape 90 degrees to the left around a center point.

Front

What is the line of reflection?

Back

The line of reflection is the line over which a shape is flipped to create its mirror image.
