Let us see about distance of a point from a plane,
In mathematics, a plane is placed at distance from a point of any horizontal, two-dimensional smooth surface. A plane is the two dimensional have a distance of a point that means zero-dimensions, a line that is known as one-dimension and a space is known as three-dimensions. A lot of mathematics may be performed in the surface of plane, particularly in the areas of geometry, trigonometry, graph theory and graphing.
Let us see about distance of point from plane:
Given a plane,
and a point X0 = (xo,y0,z0),the normal to the plane is given by,
and a vector from the plane to the point is given by,
Projecting W onto V gives the distance D from the point to the plane as,
This equation is known as the distance of a point from a plane.
1) Find the distance from the point P = (2, 2, 4) for the plane 2x +2y + 3z + 4 = 0.
Solution:
We use formula from the distance of a point from a plane.
From the above equation we substitute for the plane A = 2, B = 2, C = 3, D = 4. From the point P, we substitute x1 = 2, y1 = 2, and z1 = 4.
Plane's distance of a point is,
2) Find the distance from the point P = (2, 3, 5) for the plane x - y + z + 5 = 0.
Solution:
We use formula from the distance of a point from a plane.
From the above equation we substitute for the plane A = 1, B =- 1, C = 1, D = 5. From the point P, we substitute x1 = 2, y1 = 3, and z1 = 5.

Properties of plane:
- Two planes may be parallel or both intersect in a line.
- A line may be parallel to a plane, intersects in point.
- Two lines at a 90 degree angle to the same plane should be parallel to each other.
- Two planes at a 90 degree angle to the similar line should be parallel to each other.
