Transformation review (Strategies)

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 translation, rotation, reflection, and dilation.

Front

Define translation in geometry.

Back

Translation is a transformation that slides a figure in a straight line from one position to another without changing its size, shape, or orientation.

Front

What is a rotation?

Back

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

Front

How does a reflection work in geometry?

Back

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

Front

What is the center of rotation?

Back

The center of rotation is the fixed point around which a figure is rotated.

Front

What happens to the coordinates of a point (x, y) when it is rotated 90° clockwise about the origin?

Back

The new coordinates will be (y, -x).

Front

What happens to the coordinates of a point (x, y) when it is rotated 180° about the origin?

Back

The new coordinates will be (-x, -y).

Front

What is the result of reflecting a point (x, y) over the y-axis?

Back

The new coordinates will be (-x, y).

Front

What is the result of reflecting a point (x, y) over the x-axis?

Back

The new coordinates will be (x, -y).
