When you translate objects/functions, you are moving them to a new point. The general rule or notation for transformation geometry is that a new point is called an image, symbolised with an apostrophe (') next to the name of a point, i.e,: As you get to higher grades, you will apply these processes to functions/graphs. Now that you are in grade 9, transformation geometry will be about creating an image of a shape by performing the above procesess. At that time, you will only be asked about these processes in the exams and they will never be covered again in class. These notes or concept, you will use until grade 12. Grade 9 syllabus introduces you to transformation geometry which involves translation, reflection, dilation and rotation. Transformation geometry involves making images or copies of an object.
