  Vector Math Point Calculation

  Posted by Thomas Frenkel on December 12, 2020 at 10:24 pm

  Hello community,

  I have a vector math problem that I was not able to solve so far and would really appreciate any kind of assistance or suggestions:

  I have three given points (A,B,C) and two 90° angles at A and C that should result in a kite square. What is left is the calculation of point D.

  I know I can calculate the angle β with the dot product, but how would I proceed from there? I can’t convert that into finding the coordinates.

  Oh…and I don’t have to account for the case of all three points being on one line – this is already impossible by design.

  Thank you very much,

  Thomas

  (first 2 images had the wrong angle name, third is correct, can’t delete images via edit?)
