m this vertex, pierces the plane of the conesbase at RR (Ex. 11), hence R^ and RT are the traces, on thisplane, of two planes which are tangent to this cone on elements A^and AT (not drawn) and hence to the cupola at the points tt andTT (Ex.11 ; 6°). The perspectives of these points are t and… … m% n^ and r, Through these points the perspective of the cupolacan be sketched. Examples for Practice. 1. In Example 9, let the axis of the cone be parallel to the horizontalplane only, and find its perspective. 2. Find the perspective, either by two, or by three planes, of a regularoctagonal…
