Understanding Transformations in Geometry

Front

What is a reflection in geometric terms?

Back

A figure that is flipped over a line of reflection.

Front

What does it mean for two figures to be similar?

Back

They have the same shape but different size.

Front

What is a rigid transformation?

Back

A transformation where all dimensions are the same after mapping.

Front

What is the image in a transformation?

Back

The figure after mapping.

Front

What is the preimage in a transformation?

Back

The figure before mapping.

Front

What is a rotation in geometry?

Back

A transformation that turns a figure around a fixed point.

Front

What is a translation in geometry?

Back

A transformation that slides a figure to a different location without changing its shape or size.

Front

What is the line of reflection?

Back

The line over which a figure is flipped in a reflection.

Front

What is the center of rotation?

Back

The fixed point around which a figure is rotated.

Front

What is the difference between rigid and non-rigid transformations?

Back

Rigid transformations preserve size and shape, while non-rigid transformations do not.
