Even numbers can be matched up in two lines. Odd numbers have one left over.
"The rule to find whether a network is traversable or not is by looking at points called nodes. Nodes are places where two or more lines meet. On these networks, the nodes are clearly shown by the black points in the diagrams. Now you are probably wondering what this has to do with the network being traversable or not. The node either would have an odd or even number of lines connected to it. Do not count the nodes with an even number of lines connected to it. Count the number of nodes with an odd number of lines connected to it. If there are no odd nodes or if there are two odd nodes, that means that the network it traversable. Networks with only two odd nodes are in a traversable path and networks with no odd nodes are in a traversable circuit."
An odd number minus an odd number is an even number.
It depends on how many sides that it has and whether of not it is regular (all the lines of the polygon are of equal length if it is a regular polygon). For regular polygons, the number of symmetry lines is the number of sides if number of sides is an odd number. Otherwise, the number of symmetry lines is double the number of sides. A square has 4 sides and 8 symmetry lines; a triangle has 3 sides and 3 symmetry lines.
it is an odd number
An odd number of lines are used in interlaced scanning because, in each field of the TV, the scanning displaces the field by a half of the area. If there were an even number of lines, it would flicker noticably.
To Ensure Interlaced Scanning
Even numbers can be matched up in two lines. Odd numbers have one left over.
1080 is the number of vertical scanning lines on the 1080i and 1080p High Definition Video modes.

27 is an odd number.

when an odd number is subtracted from an odd number the answer is an even number.
odd
it is an odd number
An odd number times an odd number is an odd number no matter which 2 odds you multiply.
