Visually 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 produce a new shape.

Front

What are the three main types of transformations?

Back

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

Front

What is translation?

Back

Translation is a transformation that slides a shape from one position to another without turning or flipping it.

Front

What is rotation?

Back

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

Front

What is reflection?

Back

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

Front

What does it mean to slide a shape?

Back

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

Front

How can you identify a rotation?

Back

You can identify a rotation by looking for a shape that has been turned around a point.

Front

What is the center of rotation?

Back

The center of rotation is the fixed point around which a shape is turned during a rotation.

Front

What is a line of reflection?

Back

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

Front

What is the difference between rotation and reflection?

Back

Rotation turns a shape around a point, while reflection flips a shape over a line.
