Reflections, Rotations, and Translations

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.

Front

What are the three main types of transformations?

Back

The three main types of transformations are reflections, rotations, and translations.

Front

Define reflection in geometry.

Back

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

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a shape around a fixed point, known as the center of rotation.

Front

What does translation mean in geometry?

Back

Translation is a transformation that slides a shape from one position to another without rotating or flipping it.

Front

What is line symmetry?

Back

Line symmetry occurs when a shape can be divided into two identical halves that are mirror images of each other.

Front

What is rotational symmetry?

Back

Rotational symmetry is when a shape can be rotated around a center point and still look the same at certain angles.

Front

How can you identify a reflection in a shape?

Back

You can identify a reflection by checking if one half of the shape is a mirror image of the other half across a line.

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 difference between a reflection and a rotation?

Back

A reflection flips a shape over a line, while a rotation turns a shape around a point.
