# If isotherms are concave towards the " north-east " direction ( 45 °), then adiabats are concave towards the " east north-east " ( 31 °).

# If adiabats and isotherms are graphed severally at regular changes of entropy and temperature, respectively ( like altitude on a contour map ), then as the eye moves towards the axes ( towards the south-west ), it sees the density of isotherms stay constant, but it sees the density of adiabats grow.

# If morality is objective and absolute, God must exist.

# If the design is symmetrical in an axis parallel to the flag pole, obverse and reverse will be identical despite the mirror-reversal, such as the Indian Flag or Canadian Flag

# If not, the obverse and reverse will present two variants of the same design, one with the hoist on the left ( usually considered the obverse side, see flag illustrations ), the other with the hoist on the right ( usually considered the reverse side of the flag ).

# If two straight lines in a plane are crossed by another straight line ( called the transversal ), and the interior angles between the two lines and the transversal lying on one side of the transversal add up to less than two right angles, then on that side of the transversal, the two lines extended will intersect ( also called the parallel postulate ).

# Associativity: If a * b and b * c are defined, then ( a * b ) * c and a * ( b * c ) are defined and equal.

# Identity: If a * b is defined, then a * b * b < sup >− 1 </ sup >
