Triangle knowing two sidelines rb, rc and the Euler line re
1) The vertex A is the intersection
between rb and rc
2) Let rb', rc' be the reflections
of re with respect to rb and rc
3) Let D be the intersection between
rb' and rc'
4) The perpendicular bisector of
AD cuts re at O
5) The circle through A centered
at O cuts rc at B and rb at C, and ABC is the requested triangle
