Front

What is a sequence of transformations?

Back

Two or more translations, reflections, or rotations that map a preimage to its image.

What is a translation in geometry?

Back

A transformation that moves every point of a shape the same distance in a given direction.

Front

What is a reflection in geometry?

Back

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

Front

What is a rotation in geometry?

Back

A transformation that turns a shape around a fixed point at a certain angle.

Front

What is the purpose of rigid transformations?

Back

To change the position or orientation of a shape without altering its size or shape.

Front

What is the difference between a preimage and an image?

Back

A preimage is the original shape before transformation, while an image is the resulting shape after transformation.

Front

What does it mean to map a shape?

Back

To apply a transformation that moves the shape to a new position or orientation.

Front

What is the effect of a reflection over the x-axis?

Back

It flips the shape vertically, changing the sign of the y-coordinates.

Front

What is the effect of a reflection over the y-axis?

Back

It flips the shape horizontally, changing the sign of the x-coordinates.

Front

What is a dilation in geometry?

Back

A transformation that changes the size of a shape but not its shape, by scaling it up or down.
