Technical Drawing - Exam Papers - Higher - 1992 - Paper 1Question 1Given the horizontal and vertical projections of two planes ABCD and ABE. A = 285 - 50 - 85 (a) Determine the dihedral angle between the planes. (b) Determine the position of a point P on the plane ABCD which shall be at a distance of 35mm from the horizontal plane and 75 mm from the vertical plane Join EP and determine the inclination of EP to the plane ABCD. (c) On a separate diagram, draw the projections of the skew lines AE and BC and show the projections of the shortest horizontal distance between them. ![]() |
