Transformations Introduction

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape to create a new shape.

Front

What are the four main types of transformations?

Back

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 a 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 the angle of rotation that returns a shape to its original position?

Back

360 degrees.

Front

Write the translation rule for moving a point (x, y) to (x + 2, y - 1).

Back

(x + 2, y - 1).

Front

Identify the transformation: A shape is flipped over a line.

Back

Reflection (Flip).

Front

Identify the transformation: A shape is moved without rotation or flipping.

Back

Translation (Slide).

Front

Identify the transformation: A shape is turned around a point.

Back

Rotation (Turn).
