Geometry Unit 1 Review: Explore Rigid Transformations

Front

What is a rigid transformation?

Back

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

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 is a translation in geometry?

Back

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

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a figure around a fixed point at a certain angle.

Front

What is the line of reflection?

Back

The line of reflection is the line over which a figure is reflected to create a mirror image.

Front

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

Back

To rotate a figure 90 degrees clockwise means to turn the figure 90 degrees to the right around a fixed point.

Front

What is the difference between a transformation and a rigid transformation?

Back

A transformation can change the size or shape of a figure, while a rigid transformation preserves both.

Front

What is the center of rotation?

Back

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

Front

What is the effect of a translation on a figure?

Back

A translation moves every point of a figure the same distance in the same direction.

Front

What is the angle of rotation?

Back

The angle of rotation is the measure of the degree through which a figure is rotated around a point.
