Transformations Review

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way to produce a new shape.

Front

What are the four main types of transformations?

Back

Translation, Rotation, Reflection, and Dilation.

Front

Define Translation in geometry.

Back

Translation is a transformation that slides a shape from one position to another without turning or flipping it.

Front

What is a Rotation?

Back

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

Front

What is Reflection in geometry?

Back

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

Front

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

Back

It means to turn the shape 90 degrees to the right around a fixed point.

Front

What does it mean to rotate a shape 90 degrees counter-clockwise?

Back

It means to turn the shape 90 degrees to the left around a fixed point.

Front

What is the line of reflection?

Back

The line of reflection is the line over which a shape 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, maintaining its orientation.

What is the effect of a 180-degree rotation?

Back

A 180-degree rotation turns a shape upside down around a fixed point.
