  1. SOLID GEOMETRY

  2. SOLID GEOMETRY Following topics will be covered in Solid Geometry ; (a) Projections of Points in space (b) Projections of Lines (Without H.T. & V.T.) (c) Projections of Planes (d) Projections of Right & Regular Solids like; (Prisms, Pyramids, Cylinder and Cone)

  3. PROJECTIONS OF POINTS

  4. Orientation of Point in Space • In quadrant I (Above H.P & In • Front of V.P.) (2) In quadrant II (Above H.P & Behind V.P.) (3) In quadrant III (Below H.P & Behind V.P.) (4) In quadrant IV (Below H.P & In Front of V.P.)

  5. Orientation of Point in Space (5) In Plane (Above H.P. & In V.P.) (6) In Plane (Below H.P. & In V.P.) (7) In Plane ( In H.P. & In front of V.P.) (8) In Plane ( In H.P. & Behind V.P.) (9) In Plane ( In H.P. & V.P.)
