If `l, m, n` are lines in the same plane such that `l` intersects `m` and `n||m` then `n` intersects `l` also

If 1;m;n are lines in the same plane such that 1 intesects m and n|m ; then 1 intersects n also.

n,l,m are three lines in the same plane.If l intersects m and nllm, then find the relation betweenl and n.

If l ,\ m,\n are three lines such that l || m\ a n d\ n_|_l , prove that n_|_mdot

If l,m and n are three straight lines such that l||m and l||n then prove that m||n .

Two lines l and m are intersect at the point O is a point on a line n passng through the passed O such that P is equidistant from l and m. find than n is the bisector of the angle formed by l and m.

If l,m,n are direction cosines of the line then -l,-m,-n can be

State which of the following statements are true (T) or which are false (F) If two lines in the same plane do not intersect, then they must be parallel. Distance between two parallel lines is not same everywhere. If m_|_l ,\ n\ _|_\ l and m\ !=n , then m n Two non-intersecting coplanar rays are parallel. No two parallel segments intersect. Every pair of lines is a pair of coplanar lines. Two lines perpendicular to the same line are parallel. A line perpendicular to one of two parallel lines is perpendicular to the other.

l, m and n are three parallel lines intersected by transversals p and q such that l, m and n cut off equal intercepts AB and BC on p (see Fig.). Show that l, m and n cut off equal intercepts DE and EF on q also

l, m and n are three parallel lines intersected by transversals p and q such that l, m and n cut off equal intercepts AB and BC on p (see Figure). Show that l, m and n cut off equal intercepts DE and EF on q also.

l, m and n are three parallel lines intersected by transversals p and q such that l, m and n cut off equal intercepts AB and BC on p (see Fig. 8.28). Show that l, m and n cut off equal intercepts DE and EF on q also.
