in Fig. 52. If this perpendicularbe made equal in length to the edge of the square, then it will be seen that thecube can be represented by drawing other perpendiculars with projections equalin length to the projections of this one and parallel to it; and by joining the upperends of them the… … Fig. 66. In Fig. 67 the plan and elevation of a regular pentagon (whose angle is 108°)is found, one edge being at 25° to the H.P. and an adjacent edge at 35° to theH.P. Following the construction shown in Fig. 65, (i), the inclined lines are foundin position at ac, ch for plans, and ac, cb for…
