Prove: jnm
nmi
according to the given information in the image. jk ii hi while jnm and lnk are vertical angles. jnm and lnk are congruent by the vertical angles theorem. because lnk and
2nmi are corresponding angles, they are congruent according to the corresponding angles theorem. finally, jnm is congruent to nmi by the transitive property of equality.
