Sterling has prepared the following twocolumn proof below. He is given that ∠OLN ≅ ∠LNO and he is trying to prove that OL ≅ ON.
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 HypotenuseLeg (HL) Postulate
7 ∠LEO ≅ ∠NEO Transitive Property of Equality
8 OL ≅ ON CPCTC
made two errors in the proof. Identify and correct the errors.
