Any geometry geniuses here? [View all]

I'm going to post a picture from Reddit, as well as a link to the thread.

The title of the thread is 'How to trim around this corner"?

I have a similar situation in which I need to form an outside corner joint where a level plane meets a sloped plane with a profiled baseboard.

In my case, it's where my dining room floor slopes down slightly to my kitchen floor. I did a quick solution years ago, but it doesn't look good. I stare at the thing every day, and I can't figure out the miter cuts.

Based on the comments in the thread, it seems like other people have this problem too. I don't really see an understandable solution in the comments, but some of them are hilarious....like "just caulk it".

I can *almost* visualize the cuts if the trim was flat with no profile, but it becomes tricky on profiled miters.

This post is kind of like a hail Mary pass for me, because all of the good old-time carpenters that I used to know have passed on, so I can't ask them. And the problem is...this is one of those things where it is very difficult to find a video or diagram that someone like me can understand.

Picture, followed by link so you can see the comments. The question is...how do you join those two pieces of trim at the corner?
