Main: Lessons consist of examples with notes and instructions, following on to increasingly difficult exercises with problem solving tasks. Lesson 8.4.4h - Combined enlargements (Two versions - Vectors - Directions).Lesson 8.4.4f - Combined enlargements (Two versions - Vectors - Directions).Lesson 8.4.3f - Negative enlargements (Two versions - Vectors - Directions).Lesson 8.4.2f - Positive enlargements (Two versions - Vectors - Directions).Lesson 8.4.1f - Describing enlargements.Lesson 8.3h - Translations (Describing and performing - with extension).Lesson 8.3f - Translations (Describing and performing).Lesson 8.2h - Rotations (Describing and performing).Lesson 8.2f - Rotations (Recognising and performing).Lesson 8.1.2h - Reflecting in a straight line (Axes, y=(-)x, x=… and y=…).Less on 8.1.2f - Reflecting in a mirror line (Mirror lines and axes) Transformation refers to the movement of objects in the coordinate plane.Lesson 8.1.1f - Symmetry (Including rotational symmetry).The worksheet could also be used independent of the PowerPoint lesson with a visualiser! These are designed to speed up the lesson (no copying down questions etc). At least two printable worksheets for students with examples for each lesson. ![]() Normal PowerPoint lessons with which you can use a clicker / mouse / keyboard to continue animations and show fully animated and worked solutions.Some images/mathematical drawings are created with GeoGebra.A collection of TWELVE FULL LESSONS on symmetry, reflections, translations, rotations and enlargements. The projected shape is then translated into a few units to the right to construct $A^ = (6, 4)$ Answer Key The pre-image, $A$, is reflected over the horizontal line. To better understand how the glide reflection works, take a look at the illustration shown below. The glide reflection does all two in no specific order. Translation is another rigid transformation that “slides” through a pre-image to project the desired image.Reflection is a basic transformation that flips over the pre-image with respect to a line of reflection to project the new image.This means that the glide reflection is also a rigid transformation and is the result of combining the two core transformations: reflection and translation. By the end of the discussion, glide reflection is going to be an easy transformation to apply in the future! What Is a Glide Reflection?Ī glide reflection is the figure that occurs when a pre-image is reflected over a line of reflection then translated in a horizontal or vertical direction (or even a combination of both) to form the new image. It covers how the order of transformations affects the glide reflection as well as the rigidity of glide reflection. This article covers the fundamentals of glide reflections (this includes a refresher on translation and reflection). The resulting change on the pre-image reflects an image that seems to have a “gliding effect,” hence the name of this transformation. The glide reflection combines two fundamental transformations: reflection and translation. To provide an analogy: imagine walking barefoot on the beach, the footprints formed exhibit glide reflection. Through glide reflection, it is now possible to study the effects of combining two rigid transformations as well. The glide reflection is a great example of a composite transformation, which means it is composed of two basic transformations.
