Sequence of Transformations

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, called the image.

Front

Define translation in geometry.

Back

Translation is a transformation that moves every point of a shape the same distance in the same direction.

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

Explain reflection in geometry.

Back

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

What is the line of reflection?

Back

The line of reflection is the line over which a shape is reflected to create a mirror image.

Front

Define dilation in geometry.

Back

Dilation is a transformation that changes the size of a shape but not its shape, by a scale factor.

What is a sequence of transformations?

Back

A sequence of transformations is a series of two or more transformations applied one after the other to a shape.

How does a 180-degree rotation affect a shape?

Back

A 180-degree rotation turns a shape halfway around a point, resulting in a shape that is upside down.

Front

What is the effect of reflecting a shape over the x-axis?

Back

Reflecting a shape over the x-axis flips it vertically, changing the sign of the y-coordinates of its points.
