Front

Define 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

Define reflection in geometry.

Back

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

Front

Define translation in geometry.

Back

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

How does a reflection affect the coordinates of a point?

Back

A reflection over the x-axis changes the sign of the y-coordinate, while a reflection over the y-axis changes the sign of the x-coordinate.

What is the angle of rotation?

Back

The angle of rotation is the measure of the degree through which a shape is rotated around the center of rotation.

Front

Can a shape undergo multiple transformations?

Back

Yes, a shape can undergo multiple transformations in sequence, such as rotating and then translating.

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

Back

A rigid transformation preserves the shape and size of a figure, while a non-rigid transformation may change the size or shape.
