Plane :-
A plane is determined uniquely if any one of the following is known:
(i) The normal to the plane and its distance from the origin is given, i.e., equation ofa plane in normal form.
(ii) It passes through a point and is perpendicular to a given direction.
(iii) It passes through three given non collinear points.
Equations of a Plane in Normal form :-
Vector form: The equation of plane in normal form is given by 𝑟⃗ ⋅𝑛⃗ =𝑑, where 𝑛⃗ is a vector which is normal to the plane.
Cartesian form: The equation of the plane is given by ax + by + cz = d, where a, b and c are the direction ratios of plane and d is the distance of the plane from origin.
Another equation of the plane is lx + my + nz = p, where l, m, and n are direction cosines of the perpendicular from origin and p is a distance of a plane from origin.
Note: If d is the distance from the origin and l, m and n are the direction cosines of the normal to the plane through the origin, then the foot of the perpendicular is (ld, md, nd).

Equation of a Plane Perpendicular to a given Vector and Passing Through a given Point
Vector form:
Let a plane passes through a point A with position vector 𝑎⃗ and perpendicular to the vector 𝑛⃗ , then (𝑟⃗ − 𝑎⃗ )⋅𝑛⃗ =0
This is the vector equation of the plane.
Cartesian form:
Equation of plane passing through point (x1, y1, z1) is given by
a (x – x1) + b (y – y1) + c (z – z1) = 0 where, a, b and c are the direction ratios of normal to the plane.
Equation of Plane in Intercept Form: If a, b and c are x-intercept, y-intercept and z-intercept, respectively made by the plane on the coordinate axes, then equation of plane is = 𝑥/𝑎+𝑦/𝑏+𝑧/𝑐=1
Cartesian form: If the equation of planes are a1x + b1y + c1z = d1 and a2x + b2y + c2z = d2, then equation of any plane passing through the intersection of planes is a1x + b1y + c1z – d1 + λ (a2x + b2y + c2z – d2) = 0
where, λ is a constant and calculated from given condition.
