Find normal vector from 3 points
WebJan 18, 2015 · We are given three points, and we seek the equation of the plane that goes through them. The method is straight forward. A plane is defined by the equation: a x + b y + c z = d. and we just need the coefficients. The a, b, c coefficients are obtained from a vector normal to the plane, and d is calculated separately. WebOct 14, 2024 · Take three points which lies on the plane, namely A = ( 4, 0, 0), B = ( 0, 0, − 12 7), C = ( 1, 0, − 9 7) then vector A B = ( − 4, 0, − 12 7) and A C = ( − 3, 0, − 9 7). Taking their cross product we get zero vector. …
