Pair of parallel lines is .......

In the given figure, name: all pairs of parallel lines

ABCD is a quadrilateral in which /_A= 60^(@), /_ B= 70^(@), /_ C =110^(@) and /_ D =120^(@) . The number of pairs of parallel lines is "________________" .

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

The angle subtended by side of a parallelogram with pair of other parallel lines is 150^(@) . If distance between parallel sides PQ and SR is 20 cm then what is the length of side RQ ?

l and m are two parallel lines intersected by another pair of parallel lines p and q. Show that △ABC≅△CDA.

The distance between the pair of parallel lines given by x^2-1005x+2006=0 is

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.
