Given: KM bisects ∠JKL.

Prove: [tex]m\angle MKL=\dfrac{1}{2}m\angle JKL.[/tex]

Proof:

1. If KM bisects ∠JKL, then ∠JKM≅∠LKM and

[tex]m\angle LKM=m\angle LKM.[/tex]

2.

[tex]m\angle JKL=m\angle JKM+m\angle LKM.[/tex]

3. At last,

[tex]m\angle JKL=m\angle JKM+m\angle LKM=m\angle LKM+m\angle LKM=2m\angle LKM,\\ \\m\angle LKM=\dfrac{1}{2}m\angle JKL.[/tex]
