Dr. Ling Man Ho Alpha, Chan Chun Hin
The teaching video series entitled ‘Points, Lines, and Planes in 3-D Figures’ is designed for S.3 students to gain an understanding of the concepts of projection of a line onto a plane, angle between a line and a plane, and angle between two planes. The teacher explains the three steps of finding the angle between two planes with examples in the video.
