... to B'A produced . We have obviously P'R = CP ( being projections of the equal
and parallel lines OS , CQ , on CR ) . Hence CŘ = CP + CP ; and therefore the
point R executes the V C resultant of the motions P and P. But CS , KINEMATICS

But the plane and position of the circle of which this projection is taken may
clearly be found so as to fulfil the condition of having the projections of the ranges
coincident with any two given mutually bisecting lines . Hence any two given
simple ...

... section of a surface is equal to that of the normal section through the same
tangent line multiplied by the secant of the inclination of the planes of the
sections . This is evident from the most elementary considerations regarding
projections .

Every orthogonal projection of an ellipse is an ellipse ( the case of a circle being
included ) . Hence , and from § 139 , we see that an ellipse remains an ellipse ;
and an ellipsoid remains a surface of which every plane section is an ellipse ;
that ...
