Identify transformations - basic

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

What are the three main types of rigid transformations?

Back

The three main types of rigid transformations are translation (slide), rotation (turn), and reflection (flip).

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 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

Explain reflection in geometry.

Back

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

Front

What does it mean for a transformation to be rigid?

Back

A rigid transformation preserves the shape and size of the figure, meaning the original and image are congruent.

Front

What is the difference between a transformation and a rigid transformation?

Back

A transformation can change the size or shape of a figure, while a rigid transformation does not change the size or shape.

Front

What is the center of rotation?

Back

The center of rotation is the fixed point around which a shape is turned during a rotation.

Front

How do you identify a translation on a graph?

Back

A translation can be identified by observing that all points of the shape move the same distance in the same direction without changing orientation.

Front

What is the angle of rotation?

Back

The angle of rotation is the measure of the degree to which a shape is turned around the center of rotation.
