Sterling has prepared the following two-column proof below. he is given that ∠oln ≅ ∠lno and he is trying to prove that ol ≅ on. triangle oln, where angle oln is congruent to angle lno step statement reason 1 ∠oln ≅ ∠lno given 2 draw oe as a perpendicular bisector to ln by construction 3 m∠leo = 90° definition of a perpendicular bisector 4 m∠neo = 90° definition of a perpendicular bisector 5 le ≅ en definition of a perpendicular bisector 6 δole ≅ δone hypotenuse-leg (hl) postulate 7 ∠leo ≅ ∠neo transitive property of equality 8 ol ≅ on cpctc sterling made two errors in the proof. identify and correct the errors.
