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.
