Transformations: Orientation and Congruence

Front

What are congruence transformations?

Back

Transformations that preserve size and shape, including rotations, translations, and reflections.

Front

What is the definition of congruence in geometry?

Back

Congruence means having the same size and the same shape.

Front

Which transformation does not preserve orientation?

Back

A rotation 90° clockwise does not preserve orientation.

Front

What does the term 'similar' mean in geometry?

Back

Similar figures have the same shape but different sizes.

Front

What do dilations preserve?

Back

Dilations preserve only orientation.

Front

What is a rotation in geometry?

Back

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

Front

What is a translation in geometry?

Back

A translation is a transformation that slides a figure in a straight line from one position to another.

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 the difference between congruent and similar figures?

Back

Congruent figures are the same size and shape, while similar figures are the same shape but different sizes.

Front

What is the scale factor in dilations?

Back

The scale factor is the ratio of the lengths of corresponding sides of similar figures.
