Intersecting and parallel lines

Given three examples each of : intersecting lines parallel lines from your environment.

From the three pairs of lines given below, identify those which uniquely determine a plane : (i) intersecting pair, (ii) parallel pair, (iii) a pair of skew lines.

From the following figure, identify, (i) Pairs of intersecting lines (ii) Parallel lines (iii) Concurrent lines

Lines are either intersecting or parallel or coincident

A : IF 5 parallel lines intersect 4 parallel lines are intersecting another set of n parallel lines is ""^(m)C_(2) xx""^(n) C_(2) .
