SPM Form 4 Mathematics_Chapter 11 Lines and Planes in 3 - Dimensions

This video consists of 5 different examples which students usually faced in doing questions related to this chapter. Students should bear in mind that plane is a flat surface of an object, 2-dimensional shape is about length and breadth thus has only one plane, whereas 3-dimensional shape includes length, breadth and height thus giving more than one surface. As this chapter is about 3-D, students may need to imagine in order to find the angle in between and understand the "shadow line" concept (orthogonal projection in proper term).
