If A = (-2, 3, 4), B = (-4, 4, 6), C = (4, 3, 5), D = (0, 1, 2) then the projection of AB on CD is

If A(2, -1, 4), B(0, 1, 5), C(4, 3, 5), D(6, 4, 3) then the projection of bar(AB) " on " bar(CD) is

If A (4, 3, 5), B (6, 4, 3), C (2, -1, 4), D (0, 1, 5) then the projection of bar(AB) " on " bar(CD) is

If A=(1, -2, -1), B= (4, 0, -3), C = (1, 2, -1), D=(2, -4, -5) , then distance between AB and CD is

If A, B, C, D are the points (2, 3, -1), (5, 2, 3), (4, 3, -5) and (-2, 1, -8) respectively, then find the projection of AB on CD.

A : If A = (1, -2, -1) B = (4, 0, - 3), C = (1,2 - 1), d = (2, -4,-5) then the distance between AB and CD is 4/3 R : The shortest distance between the skew lines r = a + sb, r = c + td is ([a - c b d])/(|b xx d|)

If points A (2, 4, 0), B(3, 1, 8), C(3, 1, -3), D(7, -3, 4) are four points then projection of line segment AB on line CD.

If points A (2, 4, 0), B(3, 1, 8), C(3, 1, -3), D(7, -3, 4) are four points then projection of line segment AB on line CD.

For A(1, -2, 4), B(5,-1,7),C(3,6,-2), D(4,5,-1) , the projection of bar(AB)" on " bar(CD) is ______
