Translations, Reflections, and Rotations

Front

What is a transformation in geometry?

Back

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

Front

What are the three main types of transformations?

Back

The three main types of transformations are translations, reflections, and rotations.

Front

What is a translation?

Back

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

Front

What is a reflection?

Back

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

Front

What is a rotation?

Back

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

Front

What does clockwise mean in terms of rotation?

Back

Clockwise means to turn in the same direction as the hands of a clock.

Front

What does counterclockwise mean in terms of rotation?

Back

Counterclockwise means to turn in the opposite direction of the hands of a clock.

Front

How do you identify a reflection in a shape?

Back

A reflection can be identified by finding a line of symmetry where one half of the shape is a mirror image of the other half.

Front

What is the effect of a translation on the coordinates of a point?

Back

In a translation, the coordinates of a point change by adding or subtracting values to the x and y coordinates.

Front

What is the center of rotation?

Back

The center of rotation is the fixed point around which a shape is turned during a rotation.
