Vector\ equation\ of\ a\ plane\ passing\ through\\\ \\ three \ non-collinear\ points\ A(a),B(b),C(c)\ is\ given\ by\\\ \\ r = ( 1-p-q) a + pb +qc\\\ \\ \\\ \\ \\\ Proof:\\\ \\Let\ the\ position\ vectors\ of\ three\ non-collinear\ points\ A,B,C\ be\ a,b,c\\\ \\The\ plane\ passing\ through\ A,B,C\ is\ parallel\ to\ AB,AC\\\ \\r=a+p\ AB\ +q\ AC\\ \\=a+p(b-a)+q(c-a)\\\ \\=(1-p-q) a + pb +qc
