If you see a rectangular table from the top, then you will find that there are ___ pair(s) of parallel line segments and _____ points of intersection.
2,4
In above table, sides AB || CD and AD || BC.
So, there are two pairs of parallel lines in the rectangular table.
A is the point of intersection of lines BA & AD.
B is the point of intersection of lines AB & BC.
C is the point of intersection of lines BC & CD.
D is the point of intersection of lines AD & DC.
So, there are 4 points of intersection.
