Translations, Rotations, & Reflections

Front

What is a translation in geometry?

Back

A translation is a transformation that slides a figure from one position to another without turning it.

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 rotation in geometry?

Back

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

Front

What does it mean for a shape to be congruent?

Back

Two shapes are congruent if they have the same size and shape, even if they are oriented differently.

Front

What is the line of reflection?

Back

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

Front

How do you identify a translation?

Back

A translation can be identified by the movement of a shape in a straight line without any rotation or flipping.

Front

What is the angle of rotation?

Back

The angle of rotation is the degree measure of how far a figure is turned around a point.

Front

What is the center of rotation?

Back

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

Front

Can a shape undergo multiple transformations?

Back

Yes, a shape can undergo multiple transformations, such as a translation followed by a rotation.

Front

What is the difference between a rotation and a reflection?

Back

A rotation turns a shape around a point, while a reflection flips it over a line.
