Geometry OT Transformations Pop Flashcard

Front

What is a transformation in geometry?

Back

A transformation in geometry is an operation that moves or changes a shape in some way to produce a new shape, called the image.

Front

Define reflection in geometry.

Back

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

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?

Back

To rotate a figure means to turn it around a fixed point, called the center of rotation, by a certain angle.

Front

What is the difference between clockwise and counterclockwise rotation?

Back

Clockwise rotation is in the direction of the hands of a clock, while counterclockwise rotation is in the opposite direction.

Front

What is a translation in geometry?

Back

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

Front

What are congruent figures?

Back

Congruent figures are figures that have the same shape and size, but may be in different positions.

Front

What is the pre-image in a transformation?

Back

The pre-image is the original figure before any transformation is applied.

Front

What is the image in a transformation?

Back

The image is the resulting figure after a transformation has been applied to the pre-image.

Front

What is a sequence of transformations?

Back

A sequence of transformations is a series of transformations applied one after the other to a figure.
