ANALYTICAL GEOMETRY - Angle of inclination

This is a video demonstrating the angle of inclination used in analytical geometry. In this video, I demonstrate how to determine the angle of inclination of a line with both a positive and negative gradient. I also demonstrate how to use the geometry rule of "the exterior angle of a triangle equals the sum of the interior opposite angles" to determine the angle of inclination. At 10:49, I model the full solution of the South African, GDE November 2019 Paper 2 (Question 4). I do hope that this video helps.
