XY and MN are the tangents drawn at the end points of the diameter DE of the circle with centre O. Prove that XY ∥ MN. Given: XY & MN are tangents DE is the diameter To prove: XY ∥ MN Proof: Since Tangent is perpendicular to radius For lines XY and MN With transversal DE ∠ YDE = ∠ NED Thus, alternate interior angles are equal ∴ Lines must be parallel Hence, XY ∥ MN Hence proved
