Real-World EXAMPLE 
Example 2     Identify Transversals
FARMING  Texas is the leading producer of livestock in the United States. A diagram of a feed lot on a farm is shown below. Identify the sets of lines to which each given line is a transversal.
a.	line k	
	If the lines are extended, line k
intersects lines p, q, r, s, t and u.

b.	line s
	lines k, l , m, and n

d.	line m
	lines p, q, r, s, t and u
