Intro to Transformations

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 four main types of transformations?

Back

The four main types of transformations are translation, rotation, reflection, and dilation.

Front

Define translation in geometry.

Back

Translation is a transformation that slides a figure from one position to another without turning it.

Front

What is rotation in geometry?

Back

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

Front

Define reflection in geometry.

Back

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

Front

What is dilation in geometry?

Back

Dilation is a transformation that changes the size of a figure but not its shape, using a scale factor.

Front

What is a pre-image?

Back

A pre-image is the original figure before any transformation is applied.

Front

What is an image in geometry?

Back

An image is the result of a transformation applied to a pre-image.

Front

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

Back

To rotate a figure 90 degrees clockwise means to turn the figure 90 degrees to the right around a fixed point.

Front

What is the line of reflection?

Back

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