Front

What is a transformation in geometry?

Back

A transformation in geometry is an operation that moves or changes a shape in some way to produce a new shape.

Front

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a shape but not its shape, by a scale factor.

Front

What is translation in geometry?

Back

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

Front

What is rotation in geometry?

Back

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

Front

What is reflection in geometry?

Back

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

Front

What is the scale factor in dilation?

Back

The scale factor is the ratio of the size of the new shape to the size of the original shape in a dilation.

Front

How does a translation affect the coordinates of a shape?

Back

In a translation, the coordinates of each point of the shape are changed by adding the same values to the x and y coordinates.

Front

What happens to the angles of a shape during a dilation?

Back

The angles of a shape remain the same during a dilation.

Front

What is the center of rotation?

Back

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

Front

What is the line of reflection?

Back

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