Triangle and 9 digits puzzle
This puzzle comes from my good friend Amrith.
Fill the three vertices and two spots on each side of the triangle with the numbers 1 thru 9 (using each only once) such that each side adds up to 20.
Multiple solutions are possible.
What approach did you use (other than simple trial and error)?
