Reflection, Rotation, Translation

Front

What is Reflection in geometry?

Back

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

Front

What is Rotation in geometry?

Back

Rotation is a transformation that turns a shape around a fixed point, called the center of rotation.

Front

What is Translation in geometry?

Back

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

Front

What does it mean to 'flip' a shape?

Back

To 'flip' a shape means to perform a reflection, creating a mirror image of the original shape.

Front

How do you describe a translation?

Back

A translation is described by how far and in which direction a shape moves, using terms like 'up', 'down', 'left', or 'right'.

Front

If a shape moves 3 units up and 4 units right, what type of transformation is this?

Back

This is a translation.

Front

What is the result of rotating a shape 90 degrees clockwise?

Back

The shape will turn 90 degrees to the right around the center of rotation.

Front

What is the line of reflection?

Back

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

Front

If triangle ABC is translated to triangle A'B'C', what does this mean?

Back

It means that triangle ABC has been moved to a new position without changing its shape or size.

Front

What is the difference between rotation and reflection?

Back

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