Transformation

In this topic, we learn to identify translations, reflections, and rotations, and use them to transform geometric shapes. We also learn solving problems by combining transformations.

Topic: Identify Transformations

  • A transformation is a change in a figure's position. Translations, rotations, and reflections are types of transformations

  • A translation is the movement of a figure from one position to another without turning it

  • A rotation is a transformation involving the turning or spinning of a figure around a fixed point called the centre of rotation

  • The mirror image produced by flipping a figure over a line is called a reflection. The line is called the line of reflection

Topic: Combining Transformations

  • A reflection flips the figure over a line to create a mirror image

  • A rotation turns the figure around a point

  • A translation slides the figure to a different location
