Angles related with lines and planes in 3D figures: Angle between two straight lines

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. In this teaching video, the teacher recaps the concepts of the angle between two straight lines to reinforce students’ prerequisite knowledge about the angle properties associated with two straight lines through visualization.
