WEEK 18: Rigid Transformations(Describe)-DAY 1 -HU

Front

What is a rigid transformation?

Back

A rigid transformation is a transformation that preserves the shape and size of a figure. The three types of rigid transformations are translation, rotation, and reflection.

Front

Define translation in geometry.

Back

Translation is a type of rigid transformation that slides a figure from one position to another without turning it.

Front

What is rotation in geometry?

Back

Rotation is a rigid transformation that turns a figure around a fixed point, known as the center of rotation, by a certain angle.

Front

Explain reflection in geometry.

Back

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

Front

What is the center of rotation?

Back

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

Front

How do you identify a translation?

Back

A translation can be identified by observing that all points of the figure move the same distance in the same direction.

Front

What does a 180° rotation look like?

Back

A 180° rotation turns a figure halfway around the center of rotation, resulting in a figure that is upside down.

Front

What is the line of reflection?

Back

The line of reflection is the line over which a figure is flipped during a reflection transformation.

Front

How can you tell if a transformation is a reflection?

Back

A transformation is a reflection if the original figure and the image are symmetrical with respect to a line.

Front

What is the difference between rotation and reflection?

Back

Rotation turns a figure around a point, while reflection flips a figure over a line.
