Translation, Rotation, Reflection, Geometric Transformations

Front

What is a 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 at a certain angle.

Front

What is a translation in geometry?

Back

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

Front

What does it mean to transform a shape?

Back

To transform a shape means to change its position, size, or orientation using operations like translation, rotation, or reflection.

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

How do you identify a rotation?

Back

You can identify a rotation by looking for a shape that has been turned around a point.

Front

What happens to the size of a shape during a translation?

Back

The size of a shape does not change during a translation; it only moves to a different location.

Front

Can a shape be reflected over a point?

Back

No, reflection is always over a line, not a point.

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 an example of a translation?

Back

Sliding a triangle 3 units to the right and 2 units up is an example of a translation.
