Co-normal Points

Statement :1 If a parabola y ^(2) = 4ax intersects a circle in three co-normal points then the circle also passes through the vertr of the parabola. Because Statement : 2 If the parabola intersects circle in four points t _(1), t_(2), t_(3) and t_(4) then t _(1) + t_(2) + t_(3) +t_(4) =0 and for co-normal points t _(1), t_(2) , t_(3) we have t_(1)+t_(2) +t_(3)=0.

STATEMENT-1 :The locus of centroid of a triangle formed by three co-normal points on a parabola is the axis of parabola. STATEMENT-2 : One of the angles between the parabolas y^(2) =8x and x^(2) = 27y is tan^(-1)((9)/(13)). STATEMENT-3 : Consider the ellipse (x^(2))/(9) + (y^(2))/(4) =1 THe product of lengths of perpendiculars drawn from foci to a tangent is 4.
