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 three main types of transformations?

Back

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

Front

Define translation in geometry.

Back

Translation is a transformation that moves every point of a shape the same distance in the same direction.

Front

Define rotation in geometry.

Back

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

Front

Define reflection in geometry.

Back

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

Front

What happens to the size of a shape during a translation?

Back

The size and shape of the figure remain unchanged during a translation.

Front

What happens to the size of a shape during a rotation?

Back

The size and shape of the figure remain unchanged during a rotation.

Front

What happens to the size of a shape during a reflection?

Back

The size and shape of the figure remain unchanged during a reflection.

Front

Can a transformation change the orientation of a shape?

Back

Yes, a rotation and a reflection can change the orientation of a shape, while a translation does not.

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.
