8th math Transformations

Front

What is a transformation in geometry?

Back

A transformation in geometry is an operation that moves or changes a shape in some way, including turning, flipping, or sliding it on a graph.

Front

What are the three main types of transformations?

Back

The three main types of transformations are translations (slides), rotations (turns), and reflections (flips).

Front

What does it mean when a dilation has a scale factor greater than one?

Back

When a dilation has a scale factor greater than one, it means the shape is enlarged.

Front

What is the term for the original shape before a transformation?

Back

The original shape before a transformation is called the pre-image.

Front

What is the term for the new shape after a transformation?

Back

The new shape after a transformation is called the image.

Front

What does reflection mean in terms of transformations?

Back

Reflection means to flip a shape over a line, creating a mirror image.

Front

What does it mean for two figures to be congruent?

Back

Two figures are congruent if they have the same shape and size.

Front

What does it mean for two figures to be similar?

Back

Two figures are similar if they have the same shape but not necessarily the same size.

Front

What is a translation in geometry?

Back

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

Front

What is a rotation in geometry?

Back

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