e quadrilateral BB^CC^ the polar q of M is easilyfound. Through A draw 5 parallel to q, and find by Pascalstheorem the intersection F of s with K. K is the circle passingthrough F and tangent at A to the perpendicular to AM\ i6o PROJECTIVE GEOMETRY. If K is tangent to s at the point S, the… … Fig. 67. Ex. 2. To construct the osculating circle at the vertex of aconic which is determined by major and minor axes. Ex. 3. To construct a parabola when the osculating circle atits vertex is known. Ex. 4. Given three tangents and two points of a conic; con-struct the conic. Dualistic problem of…
