Transformations. 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 dilation in geometry?

Back

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

What does it mean to map a shape?

Back

To map a shape means to apply a transformation to it, resulting in a new position or orientation of the shape.

Front

What is the effect of a 180-degree rotation around the origin on a point (x, y)?

Back

The image of the point (x, y) after a 180-degree rotation around the origin is (-x, -y).

Front

Describe the sequence of transformations: reflection followed by translation.

Back

First, reflect the shape over a line, then move the reflected shape in a specified direction and distance.
