Answer 1

The two column proof has shown that ΔJKL ≅ ΔMNL by AAS (Angle Angle Side Congruence)

How to use two column proof?

The two column proof to show that ΔJKL ≅ ΔMNL is as follows:

Statement 1: KN bisects JM

Reason 1: Given

Statement 2: JK ║ MN

Reason 2: JL ≅ LM

Statement 3: ∠K ≅ ∠N

Reason 3: Alternate Interior angles

Statement 4: ∠J ≅ ∠M

Reason 4: Alternate Interior angles

Statement 5: ΔJKL ≅ ΔMNL

Reason 5: AAS (Angle Angle Side Congruence)
