I'm stuck in a couple of puzzles and cannot find any help online, all of the YouTube videos of solutions are for a like different version of the app that does not contain the same puzzles.

Alright, so I've somehow worked my way up to 10.9 without the need of too many walkthrough videos. Of course, I try to finish the level as best I can but when I can't after ~25 attempts, I go looking for a video to at least get a semblance of an answer. The only problem is that every video:

• is actually covering a completely different level (i.e. 3 degree angle)

• is just a text post in Korean (yes there were multiple)

• doesn't actually help because they're on a device that doesn't highlight points when they're used (eg tablet, phone)

I've been stuck on this one for about a week and a half now and all I know is that you start like this:

Did anyone solve this? 7e 7l is fairly easy but there‘s absolutely no way that there are more than 2 solutions, like it says there are three. Only two vertices are given and the other 2 vertices can only be in a position upper and lower to these in perpendicular. Can anyone chime in?

Does anyone know the new/updated 13e solution for this level? Searched it on google to no avail. Been so long and I can’t solve it, I give up. It’s my only missing star to unlocking last three sections.

Euclidea app was updated. There is a new Eta 7.8. Link https://imgur.com/gallery/bBHCDfq

I can't get the E star and I need some kind of hint.

I need help to find the Last V star in beta, can somebody help me? I've already found the 2.3 one

9.1 Minimum distance.

So you draw a circle between the 2 lines' vertice and the given point, and then you draw 2 circles seemingly arbitrary (other than that their origin lies on the 2 lines) and then you connect the overlapping points from the first circle and the the 2 secondary circles.

Why would that give me the "minimum"?
