Distance Between Point and Plane – Formula, Definition With Examples

Understanding the concept of distance between a point and a plane is a fundamental part of any online math program for kids. It is a crucial element in the study of geometry and spatial understanding, which are key components in math education for children. This concept helps in developing a child’s ability to visualize and comprehend the spatial relationships in math.

What is Distance Between Point and Plane?

The distance between a point and a plane in math for kids refers to the shortest line that can be drawn from a given point to a flat surface (plane). It’s a basic yet important concept in geometry, particularly in understanding the properties of shapes and spaces, which are essential in many math tutor for kids.

Distance Between Point and Plane: Definition and Formula

In math tutoring for kids, we explain that the formula to calculate the distance $d$ from a point P(x1​,y1​,z1​) to a plane with the equation $Ax+By+Cz+D=0$ is:

d=(|Ax₁​+By₁+Cz₁​+D|)/√(A²+B²+C²)​

This formula is a key part of the curriculum in math programs for children, simplifying the concept of spatial distance into a manageable equation.

Derivation of the Distance Formula

In math education for kids, we derive this formula using basic principles of vector calculus and geometry, making it a great example for teaching mathematical reasoning and problem-solving skills in math classes for kids.

How to Calculate Distance from a Point to a Plane

Calculating this distance involves identifying the coefficients and coordinates, then substituting them into our formula. This process is a practical application of algebra and geometry, often used in math tutoring for kids to enhance problem-solving skills.

Examples on Distance Between Point and Plane

1. Example 1: For a plane $2x-3y+4z+10=0$ and a point $P(1,2,3)$, we calculate the distance in our math sessions for kids.
2. Example 2: Using the plane $x+2y-2z-4=0$ and point $Q(-1,0,2)$, we illustrate another example in our math curriculum for children.

Practice Problems: Calculating Distance Between Point and Plane

1. Determine the distance from $(3,-2,5)$ to $x-y+z-6=0$.
2. Find the distance between $(-1,4,2)$ and $3x+2y-z+1=0$.
