Show that all chords of a parabola which subtend a right angle at the vertex pass through a fixed point on the axis of the curve.

Chord of the parabola y^2+4y=(4)/(3)x-(16)/(3) which subtend right angle at the vertex pass through:

A normal chord of the parabola y^(2)=4ax subtends a right angle at the vertex if its slope is

Show that all chords of the curve 3x^(2)-y^(2)-2x+4y=0, which subtend a right angle ax the origin,pass through a fixed point.Find the coordinates of the point.

All chords of the parabola y^(2)=4x which subtend right angle at the origin are concurrent at the point.

A variable chord of the parabola y^(2)=24x which subtend 90^(@) angle at its vertex always passes through a fix point whose distance from origin is:

A chord of parabola y^(2)=4ax subtends a right angle at the vertex The tangents at the extremities of chord intersect on

The normal chord of the parabola y^(2)=4ax subtends a right angle at the vertex.Then the length of chord is
