| Answer» TION:Given: A circle with Centre O, P is the midpoint of Arc APB. PT is a tangent to the circle at P.To PROVE: AB || PTConstruction: join OA ,OB, & OPProof: OP ⟂PT[Radius is ⟂ to tangent through point of contact]∠OPT= 90°Since P is the midpoint of Arc APBArc AAP =arc BP∠AOP = ∠BOP∠AOM= ∠BOMIn ∆ AOM & ∆BOMOA= OB= r OM = OM (Common)∠AOM= ∠BOM (proved above)∠AOM≅∠BOM (by SAS congruency AXIOM)∠AMO = ∠BMO (c.p.c.t)∠AMO + ∠BMO= 180°∠AMO = ∠BMO= 90°∠BMO = ∠OPT= 90°But, they are corresponding angles.
