Question

If the straight lines $a_1 x+b_1 y+c_1=0$, $a_1 x+b_1 y+c_2=0, a_2 x+b_2 y+d_1=0$ and $a_2 x+b_2 y+d_2=0$ are the sides of rhombus, then

Accepted Answer

$\left(a_2^2+b_2^2\right)\left(c_1-c_2\right)^2=\left(a_1^2+b_1^2\right)\left(d_1-d_2\right)^2$

Answer

$\left(a_1^2+b_1^2\right)\left|d_1-d_2\right|=\left(a_2^2+b_2^2\right)\left|c_1-c_2\right|$

Answer

$\left(a_2^2+b_2^2\right)\left(d_1-d_2\right)^2=\left(a_1^2+b_1^2\right)\left(c_1-c_2\right)^2$

Answer

$\left(a_1^2+b_1^2\right)\left|c_1-c_2\right|=\left(a_2^2+b_2^2\right)\left|d_1-d_2\right|$
