Assertion (A): A(x_(1),y_(1),z_(1)), B(x_(2),y_(2),z_(2)). The projection of AB on the line with D.C's (l,m,n) is l(x_(2)-x_(1)) +m(y_(2)-y_(1))+n(z_(2)-z_(1)) Reason (R ) : The projection of the join of A (x_(1),y_(1),z_(1)), B(x_(2),y_(2),z_(2)) on yz plane is sqrt((y_(2)-y_(1))^(2)+(z_(2)-z_(1))^(2))

Assertion (A): A(x_(1),y_(1),z_(1)), B(x_(2),y_(2),z_(2)). The project

1.	Assertion (A): A(x_(1),y_(1),z_(1)), B(x_(2),y_(2),z_(2)). The projection of AB on the line with D.C's (l,m,n) is l(x_(2)-x_(1)) +m(y_(2)-y_(1))+n(z_(2)-z_(1)) Reason (R ) : The projection of the join of A (x_(1),y_(1),z_(1)), B(x_(2),y_(2),z_(2)) on yz plane is sqrt((y_(2)-y_(1))^(2)+(z_(2)-z_(1))^(2))
