Unit 2 Vocabulary: Transformations

Front

What is a transformation in geometry?

Back

A transformation is a change in the position, size, or shape of a figure.

Front

True or False: A transformation results in a new shape.

Back

False. A transformation does not create a new shape; it alters the existing shape.

Front

What are the types of transformations?

Back

The main types of transformations are translation, rotation, reflection, and dilation.

Front

What is a translation?

Back

A translation moves a shape from one location to another without changing its size, shape, or orientation.

Front

What is a rotation?

Back

A rotation turns a shape around a fixed point at a certain angle.

Front

What is a reflection?

Back

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

Front

What is a dilation?

Back

A dilation resizes a shape by a scale factor, either enlarging or reducing it.

Front

How do you write an ordered pair?

Back

An ordered pair is written as (x, y), where x is the horizontal coordinate and y is the vertical coordinate.

Front

What does the term 'corresponding sides' mean?

Back

Corresponding sides are sides in two shapes that are in the same relative position.

Front

What does 'corresponding angles' refer to?

Back

Corresponding angles are angles in two shapes that are in the same relative position.
