Unit 6: Lines and Planes

ID. 11. 12. 13. 'I'ruelf F alse Indicate "nether the statement is true orfafse. A normal vector to a line is parallel to that line. There is no symmetric form for the equation of a plane. A plane written in sealar form can be written in vector form. In three-space there are two possibilities for the intersection of two lines. A line will never intersect with a plane. Completion Complete each statement. 1?. In three-space, if two lines are not parallel and do not intersect, they are called 18. If three planes intersect in a point then the triple scalar product of their normal zero. 19. When algebraically determining the intersection of a plane and a line, if the result is I] = 0. then
