Given are two points, $P1(x_1, y_2)$ and $P2(x_2, y_2)$, and distance $a$. Now I want to find the two points $T1$ and $T2$.
$$d(P1,T1) = d(P2, T1) = a = d(P1,T2) = d(P2, T2)$$
Eg: (T1 and T2 are my two points I want to find)
T1 /|\ len = a / | \ len = a / |L \ P1 ------ P2 \ | / len = a \ | / len = a \|/ T2
len = a The distance between the points is given (they are all the same ($a$))
L Angle of 90 degrees.
I've been trying to solve this equation for an hour. I need this for an application, so I need an abstract formulla, in which I can insert the given $x_1, y_1, x_2, y_2$.
