Transformation

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

Translation, Rotation, Reflection, Dilation.

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

What is a rotation?

Back

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

Front

What is reflection in geometry?

Back

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

Front

Define dilation in geometry.

Back

Dilation is a transformation that changes the size of a shape but keeps its proportions the same.

Front

What does it mean for figures to be congruent?

Back

Congruent figures have the same shape and size.

Front

What does it mean for figures to be similar?

Back

Similar figures have the same shape but may have different sizes.

Front

What is the image in a transformation?

Back

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

Front

If a shape is rotated 90 degrees clockwise, what happens to its orientation?

Back

The shape turns to the right, changing its orientation.
