tickle the middle and see which end laughs.
Depends on the worm, common earthworm, has a wider band at the head end
the top
tickle him in the middle (first top)
(1,head,head),(1,head,tail),(1,tail,head),(1,tail,tail) (2,head,head), (2,head,tail),(2,tail,head),(2,tail,tail), (3,head,head), (3,head,tail),(3,tail,head),(3,tail,tail), (4,head,head), (4,head,tail),(4,tail,head),(4,tail,tail), (5,head,head), (5,head,tail),(5,tail,head),(5,tail,tail), (6,head,head), (6,head,tail),(6,tail,head),(6,tail,tail),
you can tell it by seeing if it has 4 legs a head and a wavy tail
Well you put it onto the floor and wait till it moves and the part that moves first is the head.
Head - Tail - Tail - Head
A and B is a vector by replacing the tail of the B on the head of the A and the join the tail of the A with the head of the B this method is called head to tail rule
I am not sure about the tail scales-but if the head of the snake is triangular it means that that particular snake hold venom in his cheeks.
we can add vectors by head to tail rule.THe head of first vector to the tell of second vector.And for the resultant vector we can add the tail of first vector to the head of second vector. we can add more than three vectors to give a resultant is equal to zero by joining head to tail rule as to form polygan .

the head to tail rule
church
nothing has only a head and a tail tadpole or coin
In addition of vector when vector A whose head is joined to the tail of the vector B and then the tail of the vector A is linked with the tail of the resultant vector and the head of the vector B is joined with the head of the resultant vector..... it means the addition of vectors are also defined the head to tail rule..
