Angle Between Two Planes

Three dimensional plane of Class 11

Angle between two planes

The angle between two planes is defined as the angle between their normals.

The angle θ between the planes Angle Between Two Planesand 3-d plane is given by

cosθ = Angle Between Two Planes

The angle θ between the planes a1x + b1y + c1z + d1 = 0 and a2x + b2y + c2z + d2 = 0 is given by
