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.

Front

What are the three main types of transformations?

Back

Translations, reflections, and rotations.

Front

What is a translation?

Back

A translation is a transformation that slides a shape from one position to another without turning it.

Front

What is a reflection?

Back

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

Front

What is a rotation?

Back

A rotation is a transformation that turns a shape around a fixed point at a certain angle.

Front

What does it mean for shapes to be congruent?

Back

Congruent shapes are identical in shape and size, but may be in different positions or orientations.

Front

How can you identify a translation?

Back

A translation can be identified by the movement of a shape in a straight line without any rotation or flipping.

Front

What is the line of reflection?

Back

The line of reflection is the line over which a shape is flipped to create a mirror image.

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

What is the angle of rotation?

Back

The angle of rotation is the degree measure of how far a shape is turned around the center of rotation.
