Calculate coordinates of 3rd point (vertex) of a scalene triangle if angles and sides are known.
Solution 1:
Thanks everyone for the help! I found the answer. The formula for which is given here (Section: Intersection of two circles. It's not in the plot, but $d$ is the euclidean distance between the centers of the circles or $d=a+b$).
a = (r02 - r12 + d2 ) / (2d)
h = r0 sinP0 (or) r1 sinP1
P2 = P0 + a ( P1 - P0 ) / d i.e., x2 = x0 + a (x1 - x0) / d (and) y2 = y0 + a (y1 - y0) / d
x3 = x2 ± h ( y1 - y0 ) / d
y3 = y2 ± h ( x1 - x0 ) / d
Solution 2:
It is enough to take the middle point of $BC$ and duplicate it. Let me explain:
Consider $M=1/2(AB+AC)$. Then $C=2BM$. Now you have the vector and its norm, so is enough to solve an equation.
