Hi!

I saw your work on a problem someone else had, so I figured I’d seek your help on my similar problem.  I was able to work out that Angle KHJ is congruent to Angle KJH as it’s part of an Isosceles Triangle, and that Segment KH is congruent to Segment KJ as it’s also part of an Isosceles triangle but I’m stuck there.  Below I’ve attached the worksheet we’re using, as well as a list of the possible “reasons” for each step of the proof.  Thanks in advance!
