Let y2=4ax be parabola and PQ be focal chord. Let T be point of intersection of tangents at P and Q. Then
1) area of circumcircle of triangle PQT is piePQ²/4
2) orthocentre of Triangle PQT will lie on tangent att vertex
3) incentre of PQT will be vertexof parabola
4) incentre of PQT will lie on directrix
