Page 134 - A pyramid having for its base a square of 2-5" side, and its axis 3-25" long, rests with one face on the horizontal plane. Draw its plan, and a sectional elevation on a vertical plane represented by a line bisecting the plan of the axis and making an angle of 60° with it. 6. Draw the plan of a school-room 36
Page 60 - Through any point in the first line draw a line parallel to the second ; the plane through these is parallel to the second line. Through the second line draw a plane perpendicular to the fore-named plane cutting the first line in a point. Through this point draw a perpendicular in the second plane to the first, and it will be perpendicular to both lines.
