Rigid Transformations Review

Front

What is a rigid transformation?

Back

A rigid transformation is a transformation that preserves the shape and size of a figure, including translations, rotations, and reflections.

What does it mean to rotate a figure 90 degrees clockwise?

Back

To rotate a figure 90 degrees clockwise means to turn the figure to the right by a quarter turn.

What is the result of rotating a figure 360 degrees?

Back

Rotating a figure 360 degrees returns it to its original position.

Front

What is the image in a transformation?

Back

The image is the new figure that results from applying a transformation to the original figure.

Front

How do you identify the original figure in a transformation?

Back

The original figure is often referred to as the pre-image, while the transformed figure is called the image.

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What does it mean to translate a figure?

Back

To translate a figure means to slide it in a straight line from one position to another without rotating or flipping it.

Front

If a figure is reflected over the y-axis, what happens to its coordinates?

Back

The x-coordinates of the points are negated, while the y-coordinates remain the same.

Front

What is the difference between a translation and a rotation?

Back

A translation slides a figure without changing its orientation, while a rotation turns a figure around a fixed point.

Front

How do you describe a translation of 3 units up and 4 units right?

Back

The translation can be described as moving each point of the figure 3 units in the positive y-direction and 4 units in the positive x-direction.
