Identify Transformations

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

Define translation in geometry.

Back

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

Front

What is reflection in geometry?

Back

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

Front

Explain rotation in geometry.

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 dilation in geometry?

Back

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

Front

Describe the effect of a translation on a shape.

Back

A translation shifts the position of a shape without changing its size, shape, or orientation.

Front

How does reflection affect the orientation of a shape?

Back

Reflection reverses the orientation of a shape, making it a mirror image across the line of reflection.

Front

What happens to a shape during a rotation?

Back

During a rotation, a shape is turned around a fixed point, and its orientation changes based on the angle of rotation.

Front

What is the center of dilation?

Back

The center of dilation is the fixed point in a dilation transformation from which distances are multiplied to enlarge or reduce a shape.

Front

How do you identify a translation on a graph?

Back

A translation can be identified on a graph by observing that all points of the shape move the same distance in the same direction.
