assuming JKM and HKL are straight lines,
do you see any similar triangles there ?

OpenStudy (rebeleco518):
I'm rather confused right now
jimthompson5910 (jim_thompson5910):
angle HJK = 65
angle KLM = 65
so angle HJK = angle KLM
jimthompson5910 (jim_thompson5910):
what other pair of angles are congruent?

OpenStudy (rebeleco518):
all of the angles are the same, right?
jimthompson5910 (jim_thompson5910):
no they aren't
OpenStudy (rebeleco518):
jk&l r the same
jimthompson5910 (jim_thompson5910):
what kind of angles are angle JKH and angle LKM ?
OpenStudy (rebeleco518):
j&l=65
k=90
h&m=unknown

jimthompson5910 (jim_thompson5910):
Assuming HKL & JKM are straight angles, then these two angles are vertical angles
|dw:1412392114684:dw|
jimthompson5910 (jim_thompson5910):
so, angle JKH = angle LKM
by the vertical angle theorem
OpenStudy (rebeleco518):
what i really don't get is what these signs mean...|dw:1412392201112:dw|
