Transformation Practice

Front

What is a transformation in geometry?

Back

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

Front

What are the four main types of transformations?

Back

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

Front

What does a translation do to a shape?

Back

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

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 at a certain angle.

Front

What is a dilation?

Back

A dilation is a transformation that changes the size of a shape but keeps its proportions the same.

Front

Which transformation does NOT preserve congruence?

Back

Dilation does not preserve congruence.

Front

What happens to the coordinates of a point (x, y) when reflected over the x-axis?

Back

The y-coordinate changes sign, resulting in the point (x, -y).

Front

If a point (x, y) is translated 6 units up, what are the new coordinates?

Back

The new coordinates will be (x, y + 6).

Front

What is the scale factor in a dilation?

Back

The scale factor is a number that describes how much a shape is enlarged or reduced during a dilation.
