Intersecting lines

From Figure,name All pairs of parallel lines. all pairs of intersecting lines.lines of whose point of intersection in P lines whose point of intersection in C lines whose point of intersection in R collinear points.

5.20, AC and BE intersect at P. AC and BC intersect at C. AC and EC intersect at C. Try to find another ten pairs of intersecting line segments. Should any two lines or line segments necessarily intersect? Can you find two pairs of non-intersecting line segments in the figure? Can two lines intersect in more than one point? Think about it.

Non-intersection lines are called...........

Form Fig.,write all pairs of parallel lines.all pairs of intersection lines.lines whose point of intersection is l. lines whose point of intersection is D .lines whose point of intersection is E .lines whose point of intersection is A. collinear points

Form Fig., write (i)all pairs of parallel lines. (ii)all pairs of intersection lines. (iii)lines whose point of intersection is l . (iv) lines whose point of intersection is D . (v) lines whose point of intersection is E . (vi) lines whose point of intersection is A .

In the given figure, name: two non-intersecting line segments

In the adjoining figure, name (i)four line segments (ii)four rays , (iii) two non-intersecting line segments

If a transversal intersects three lines than number of intersecting points will be :

In Fig.,name: Five line segments.(ii) Five rays Non-intersection line segments
