SPM Form 5 Mathematics_Chapter 03 Transformation III

Transformation chapter includes Translation, Enlargement and Rotation.

1. Translation
The video below let students understand about the basic of translation where students will learn how to move the coordinate or triangle with the use of translation format. Also, this video explains the meaning of T². Anyway, students should always bear in mind that translation is JUST ABOUT MOVING WITHOUT rotating or resizing, thus every point of the shape must move in same distance and direction.

2. Enlargement

The video below is to let students learn about the basic skill in finding out the center point of enlargement and also the scale factor. Students should bear in mind that enlargement is a transformation which changes ONLY the size of an object and NOT the shape.

After the basic of enlargement, here comes something more challenging. In the video below, students will be exposed to different type of scale factors including positive, negative and even fraction. Students will be taught on how to find the center point of enlargement besides the area of image and object. Not to mention that it is important to write a full description in order to get full marks in the subquestion of this section.

3. Rotation

As for rotation, it means rotate/turning around at a given center thus the distance from the center to any point on the shape stays the same. Different students adapt to different learning method, therefore in this subsection, two methods are recorded in two videos below. Students can look into different way of solving the "Rotation" question.

Method 1
The method used here is somehow "creative" in finding a rotation point, some of the students may find this confusing, if so, please look into method 2.

Method 2

Students learn to find the rotation point using the "translation method" in this video. The idea come from the "base vector" method in IGSCE maths, which is easier to understand and apply. Although, this is not a proper method but it is an useful method in solving rotation.

Last video on rotation which expose more rotation examples to students. At the same time, students will also learn about finding center point with the use of compass. This video is important for students to fully understand about rotation.

Finally, one last video on transformation chapter  to let students learn to solve the transformation question and obtain 12 marks in Paper 2. =)
