Content covered in this Identifying Transformations lesson:

  • In this lesson, you will learn about Identifying Transformations – part of the Transformation Geometry topic covered in Term 4 of the Grade 9 Mathematics curriculum (CAPS).

Concepts you will learn in this Identifying Transformations lesson:

  • Summary of Transformation Rules: A quick-reference guide covering all the rules for Transformations on the Coordinate Plane.

  • Translations (Shifts)

  • Reflections: in the x-axis, y-axis, line y = x, and line y = -x

  • Rotations: 90 degrees and 180 degrees about the origin

  • Enlargements and Reductions (Dilations): about the origin

  • Practice Identifying Transformations: Exercises where students are given the coordinates of a point and its image and must determine the correct transformation applied on the coordinate plane (e.g., rotation, reflection, translation, or enlargement/reduction).

Lesson format:

  • During the video, I spend time teaching and explaining about the concepts covered in the lesson.
  • I give full examples where I show you how to answer problems, showing all working out.
  • You will have a chance to work on practice examples with a timer – this will help you to get used to working with a time limit (a necessary skill for when you need to do tests and exams).
  • I go through all the practice examples in detail after you have had time to complete them, so that you can see how you did – and where you went wrong if you made mistakes.

Get the worksheet that goes with this lesson

The worksheet includes the examples I go through in the lesson – and in some cases there may be sections that you can fill in on the worksheet instead of needing to copy everything down during the lesson (like tables etc).

The worksheet also comes with an extra exercise for you to use to practice the concepts taught in this lesson after you have finished the video.

Additionally, the worksheet includes answer sheets – with fully worked out solutions, so you can check your work and see how to complete the problems in the exercise step-by-step.
