They are additive inverses of each other. They are often called opposites, but that is not good practise. You can have multiplicative inverses (1/2 and 2 because they multiply to 1), and will you call them opposites also?
By numbers at the same distance but on opposite sides of zero.
These two numbers are:* At opposite sides of the number zero, and* At the same distance from the number zero.
A quadrilateral with opposite sides parallel & having unequal diagonals.The distance of diagonals/sides is calculated by the distance formula.
l v _______ / \ ---> / \ <-- / \ \ / --> \ / <--- \_______/ ^ l the sides marked with the same number of dashes in the arrows are the opposite sides
There are four edges that join this side to the opposite side.They are all equal length. That could give us a clue.The distance between two opposite sides is just the length of any edge of the cube.
By numbers at the same distance but on opposite sides of zero.
You could call them a pair of additive inverses.
These two numbers are:* At opposite sides of the number zero, and* At the same distance from the number zero.

Two numbers that are the same distance from zero on the number line but are on opposite sides of zero are opposite numbers, or opposites. The opposite of a number is called its additive inverse. The opposite of 78 is -78.
A quadrilateral with opposite sides parallel & having unequal diagonals.The distance of diagonals/sides is calculated by the distance formula.

Opposite vertices are two vertices of any polygon with an even number of sides that have the same number of sides between them.
Any polygon with an even number of sides can have opposite sides that are congruent and parallel.
There are many such shapes. Any polygon with an even number of sides can have opposite sides that meet the above requirements.
it can be in any shape with even number of sides.
