Identify the Type of Transformation

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 four main types of transformations?

Back

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

Front

What is translation?

Back

Translation is a transformation that moves a shape from one location to another without changing its size, shape, or orientation.

Front

What is rotation?

Back

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

Front

What is reflection?

Back

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

Front

What is dilation?

Back

Dilation is a transformation that changes the size of a shape but keeps its proportions the same, either enlarging or reducing it.

Front

How does a translation affect the coordinates of a point?

Back

In a translation, the coordinates of a point (x, y) change to (x + a, y + b), where a and b are the horizontal and vertical shifts.

Front

What happens to a shape during a rotation?

Back

During a rotation, the shape maintains its size and shape but changes its position based on the angle of rotation.

Front

What is the line of reflection?

Back

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

Front

How do you identify a dilation?

Back

A dilation can be identified by a scale factor, which indicates how much larger or smaller the shape becomes.
