T-junction is not an angle issue. It's a question about surfaces next to eachother.
Have you found the LDraw Wiki pages?

Hello Magnus,
Thank you for your reply. I was mainly concerned with the use of quadrilaterals instead of triangles. As I have seen some patterns that have used triangles although quadrilaterals would have been possible.
I thought that using quadrilaterals was uncommon or considered bad style.
I was aware of the site you mentioned. I try to avoid T-junctions. In the picture with the triangle and quadrilateral, there could be a problem because point D is not part of the triangle and the shapes are not connected at that point. There could then be a gap here due to rounding errors.
Greetings
Manfred
