" 19.Show that if two chords of a circle bisect one another they must be diameters."

Every chord of a circle is a diameter.

AC and BD are chords of a circle that bisect each other.Prove that: AC and BD are diameters ABCD is a rectangle.

If two chords having lengths a^2- 1 and 3 (a + 1), where a is a constant of a circle bisect each other, then the radius of the circle is :
