Question

What are the conditions that the planes a1x+b1y+c1z=d1anda2x+b2y+c2z=d2 are (i) parallel (ii) perpendicular to each other?

Answer 1

if planes are perpendicular then

a1.a2+b1.b2+c1.c2=0

if planes are parallel then

a1=a2

b1=b2

c1=c2

Answer 2

If perpendocular then a1/a2 =b1/b2=c1/c2
