FLASHCARD - Name the Transformation

Front

What is a transformation in geometry?

Back

A transformation in geometry 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 translation, rotation, and reflection.

Front

Define translation in geometry.

Back

Translation is a transformation that moves every point of a shape the same distance in the same direction.

Front

Define rotation in geometry.

Back

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

Front

Define reflection in geometry.

Back

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

Front

What is the line of reflection?

Back

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

Front

How do you identify a translation?

Back

A translation can be identified by the movement of a shape without changing its size, shape, or orientation.

Front

What does it mean to rotate a shape 90 degrees clockwise?

Back

Rotating a shape 90 degrees clockwise means turning the shape 90 degrees to the right around a fixed point.

Front

What is the difference between a reflection over the x-axis and the y-axis?

Back

A reflection over the x-axis flips the shape vertically, while a reflection over the y-axis flips the shape horizontally.

Front

How can you tell if a transformation is a reflection?

Back

A transformation is a reflection if the original shape and the new shape are mirror images across a line.
