A reflexion
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.
opposite and adjacent
rectangle
linear pair ^^
A rhombus (4 congruent sides, diagonals perpendicular)that is not also a square (no right angles), andis also a parallelogram (opposite sides parallel and congruent, opposite angles congruent). It is also a quadrilateral, which has 4 sides.
Opposite numbers.
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.
By numbers at the same distance but on opposite sides of zero.
They are the additive inverses of each other.
These two numbers are:* At opposite sides of the number zero, and* At the same distance from the number zero.
If two numbers have opposite signs then they are at the same distance from zero but on opposite sides of it. Conventionally, positive numbers are to the right of the zero or above it whereas negative numbers are to the left or below.
A quadrilateral with opposite sides parallel & having unequal diagonals.The distance of diagonals/sides is calculated by the distance formula.
That's called a parallelogram.
parallels
A parallelogram with opposite parallel sides would fit the given description.
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.
This is called a Parallelogram. Each pair of opposite sides will then be the same length. If all four sides are the same length, and opposite sides are parallel, then it is a rhombus. NB: If all four sides are the same length then the opposite sides must be parallel.
