Transformations Introduction

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, and Dilation.

Front

What happens to a shape during a dilation with a scale factor less than 1?

Back

The shape gets smaller.

Back

The shape gets bigger.

Front

What is a translation in geometry?

Back

A translation is a transformation that slides a shape from one position to another without turning it.

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.

Front

What is the effect of a translation on the size and shape of a figure?

Back

A translation does not change the size or shape of a figure; it only changes its position.

Front

How do you identify a reflection transformation?

Back

A reflection transformation can be identified by the presence of a line of symmetry where the shape is mirrored.

What is the formula for translating a point (x, y) by (a, b)?

Back

The new point will be (x + a, y + b).
