Roberts Math 8 Transformations

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.

Front

What are the three main types of transformations?

Back

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

Front

What is a translation?

Back

A translation is a transformation that moves a shape to a different location without changing its size, shape, or orientation.

Front

What is a rotation?

Back

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

Front

What is a reflection?

Back

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

Front

What does it mean for shapes to be congruent?

Back

Shapes are congruent if they have the same size and shape, meaning they can be transformed into each other through translations, rotations, or reflections.

Front

What is a pre-image?

Back

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

Front

What is an image in geometry?

Back

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

Front

What is the difference between a translation and a reflection?

Back

A translation moves a shape without changing its orientation, while a reflection flips a shape over a line, changing its orientation.

Front

What is the center of rotation?

Back

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